Analysis on water inflow in underwater tunnel and determination of reasonable security coping thickness
摘要
Abstract
Specific to the hydrogeology and engineering geology of the construction site of a certain underwater tunnel in a city, FLAC3D numerical method is employed for the numerical simulation, which shown that water inflow in the tunnel changes with time. Besides, it has analyzed the relationship between water yield and coping thickness as well as forecasted the time of being unsupported after the tunnel is excavated. Researches indicate that the key of constructing underwater tunnels safely is taking a comprehensive consideration about the security coping thickness and the time interval between excavation and support. The result provides a reference for its construction organization design and waterproof and drainage design.关键词
