Research on the Mechanism and Treatment of Water Inrush Disaster in Composite Stratum Tunnel
The geological conditions in Qingdao are complex,and the tunnel construction process is often influenced by the water-rich sand layer and fracture zone.Taking the tunnel project of Jingsha section of Qingdao metro as the research case,the construction of the tunnel in water-rich composite strata is analyzed by establishing the finite element model in view of the water inrush disaster of the tunnel and the ground collapse thereout,and the changes of the surrounding rock stress and pore water pressure of the tunnel are studied.In combination with the on-site conditions and numerical simulation results,the causes of the water inrush in the tunnel are analyzed and the treatment measures are put forward.
