| 520 | |a Abstract Currently, the water inrush hazards during tunnel construction, the water leakage during tunnel operation, and the accompanying disturbances to the ecological environment have become the main problems that affect the structural safety of tunnels in water-rich regions. In this paper, a tunnel seepage model testing system was used to conduct experiments of the grouting circle and primary support with different permeability coefficients. The influences of the supporting structures on the water inflow laws and the distribution of the water pressure in the tunnel were analyzed. With the decrease in the permeability coefficient of the grouting circle or the primary support, the inflow rate of water into the tunnel showed a non-linear decreasing trend. In comparison, the water inflow reduction effect of grouting circle was much better than that of primary support. With the increase of the permeability coefficient of the grouting ring, the water pressure behind the primary lining increases gradually, while the water pressure behind the grouting ring decreases. Thus, the grouting of surrounding rock during the construction of water-rich tunnel can effectively weaken the hydraulic connection, reduce the influence range of seepage, and significantly reduce the decline of groundwater. Meanwhile, the seepage tests at different hydrostatic heads and hydrodynamic heads during tunnel operation period were also conducted. As the hydrostatic head decreased, the water pressure at each characteristic point decreased approximately linearly, and the water inflow rate also had a gradual downward trend. Under the action of hydrodynamic head, the water pressure had an obvious lagging effect, which was not conducive to the stability of the supporting structures, and it could be mitigated by actively regulating the drainage rate. Compared with the hydrostatic head, the hydrodynamic head could change the real-time rate of water inflow to the tunnel and broke the dynamic balance between the water pressure and water inflow rate, thereby affecting the stress state on the supporting structures. | ||

In this paper, a tunnel seepage model testing system was used to conduct experiments of the grouting circle and primary support with different permeability coefficients. The influences of the supporting structures on the water inflow laws and the distribution of the water pressure in the tunnel were analyzed. With the decrease in the permeability coefficient of the grouting circle or the primary support, the inflow rate of water into the tunnel showed a non-linear decreasing trend. In comparison, the water inflow reduction effect of grouting circle was much better than that of primary support. With the increase of the permeability coefficient of the grouting ring, the water pressure behind the primary lining increases gradually, while the water pressure behind the grouting ring decreases. Thus, the grouting of surrounding rock during the construction of water-rich tunnel can effectively weaken the hydraulic connection, reduce the influence range of seepage, and significantly reduce the decline of groundwater. Meanwhile, the seepage tests at different hydrostatic heads and hydrodynamic heads during tunnel operation period were also conducted. As the hydrostatic head decreased, the water pressure at each characteristic point decreased approximately linearly, and the water inflow rate also had a gradual downward trend. Under the action of hydrodynamic head, the water pressure had an obvious lagging effect, which was not conducive to the stability of the supporting structures, and it could be mitigated by actively regulating the drainage rate.

Under the action of hydrodynamic head, the water pressure had an obvious lagging effect, which was not conducive to the stability of the supporting structures, and it could be mitigated by actively regulating the drainage rate. Compared with the hydrostatic head, the hydrodynamic head could change the real-time rate of water inflow to the tunnel and broke the dynamic balance between the water pressure and water inflow rate, thereby affecting the stress state on the supporting structures.

In this paper, a tunnel seepage model testing system was used to conduct experiments of the grouting circle and primary support with different permeability coefficients. The influences of the supporting structures on the water inflow laws and the distribution of the water pressure in the tunnel were analyzed. With the decrease in the permeability coefficient of the grouting circle or the primary support, the inflow rate of water into the tunnel showed a non-linear decreasing trend. In comparison, the water inflow reduction effect of grouting circle was much better than that of primary support. With the increase of the permeability coefficient of the grouting ring, the water pressure behind the primary lining increases gradually, while the water pressure behind the grouting ring decreases. Thus, the grouting of surrounding rock during the construction of water-rich tunnel can effectively weaken the hydraulic connection, reduce the influence range of seepage, and significantly reduce the decline of groundwater. Meanwhile, the seepage tests at different hydrostatic heads and hydrodynamic heads during tunnel operation period were also conducted. As the hydrostatic head decreased, the water pressure at each characteristic point decreased approximately linearly, and the water inflow rate also had a gradual downward trend. Under the action of hydrodynamic head, the water pressure had an obvious lagging effect, which was not conducive to the stability of the supporting structures, and it could be mitigated by actively regulating the drainage rate. Compared with the hydrostatic head, the hydrodynamic head could change the real-time rate of water inflow to the tunnel and broke the dynamic balance between the water pressure and water inflow rate, thereby affecting the stress state on the supporting structures.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Water-rich tunnel</subfield><subfield

Seepage field distribution and water inflow laws of tunnels in water-rich regions |
| abstract |
Abstract Currently, the water inrush hazards during tunnel construction, the water leakage during tunnel operation, and the accompanying disturbances to the ecological environment have become the main problems that affect the structural safety of tunnels in water-rich regions. In this paper, a tunnel seepage model testing system was used to conduct experiments of the grouting circle and primary support with different permeability coefficients. The influences of the supporting structures on the water inflow laws and the distribution of the water pressure in the tunnel were analyzed. With the decrease in the permeability coefficient of the grouting circle or the primary support, the inflow rate of water into the tunnel showed a non-linear decreasing trend. In comparison, the water inflow reduction effect of grouting circle was much better than that of primary support. With the increase of the permeability coefficient of the grouting ring, the water pressure behind the primary lining increases gradually, while the water pressure behind the grouting ring decreases. Thus, the grouting of surrounding rock during the construction of water-rich tunnel can effectively weaken the hydraulic connection, reduce the influence range of seepage, and significantly reduce the decline of groundwater. Meanwhile, the seepage tests at different hydrostatic heads and hydrodynamic heads during tunnel operation period were also conducted. As the hydrostatic head decreased, the water pressure at each characteristic point decreased approximately linearly, and the water inflow rate also had a gradual downward trend. Under the action of hydrodynamic head, the water pressure had an obvious lagging effect, which was not conducive to the stability of the supporting structures, and it could be mitigated by actively regulating the drainage rate. Compared with the hydrostatic head, the hydrodynamic head could change the real-time rate of water inflow to the tunnel and broke the dynamic balance between the water pressure and water inflow rate, thereby affecting the stress state on the supporting structures. © Science Press, Institute of Mountain Hazards and Environment, CAS and Springer-Verlag GmbH Germany, part of Springer Nature 2022 |
