Abstract
To study the impact of the insertion ratio of suspended water stop curtains on the surrounding environment of foundation pits in water rich areas,this paper uses finite element numerical analysis method.Taking a suspended water stop curtain foundation pit project under con-struction in the water rich strata area of the Yangtze River floodplain as an example,the excavation model of the foundation pit and the seepage stress coupling foundation pit model are analyzed.By comparing the surrounding surface settlement of different models,the influence of seepage on the excavation deformation of the foundation pit is obtained.Based on the seepage stress coupling model,the insertion ratio of the water stop curtain is changed,and the variation law of the total water inflow of the foundation pit and the maximum surrounding surface settlement with the insertion ratio of the curtain is given under different factors affecting the depth of the curtain.The results indicate that the settlement caused solely by excavation and stress release in the formation is very small;For a foundation pit excavation model considering seepage stress coupling,the surface settlement around the excavation model will increase,and precipitation has a significant impact on the surface settlement around the foundation pit.As the insertion ratio increases,the trend of the maximum water inflow of the foundation pit and the surrounding surface settle-ment is basically consistent,showing a linear decrease.关键词
