摘要
Abstract
Taking the super large foundation pit in Huaqiang North Station of Shenzhen Metro Line 7 as the engineering background,the laws how the foundation pit dewatering affects the pit and the adjacent buildings were simulated and analyzed by means of FLAC3D fluid-structure interaction.Through analyzing and comparing the effects of precipitation amount on the pit deformation and the uneven settlement and inclination of adjacent buildings,the general tendency was revealed that the lateral displacement of pit,the uneven settlement and inclination of adjacent buildings will increase with the single-step precipitation;the follow-up effect of dewatering is more significant than that arising in the previous period.关键词
