降水影响下地下连续墙应力-应变模型研究

对深基坑施工前期降水影响下地下连续墙的受力进行分析,重点考量了地下水的静水压力及渗流压力对连续墙的影响。以Saenz模型和地下水渗流模型及Darcy公式为基础,对天津地铁二号线青年路站工程条件进行分析概化,建立了地下水作用下连续墙墙体的应力-应变模型,为地下水影响下连续墙稳定性的量化研究提供了依据。

Study on Stress-Strain Model of Concrete Diaphragm Wall under Rainfall

The stress of concrete diaphragm wall under rainfall is analyzed in pre-stage of deep foundation pit construction,and the influence of static pressure and seepage pressure of underground water is measured on concrete diaphragm wall.In this paper,based on Saenz model,underground water seepage model and Darcy formula,engineering condition of Youth Road Station of Tianjin Metro No.2 Line is generalized and the stress-strain model of concrete diaphragm wall under underground water is established,which provides basis for quantitative research of diaphragm wall stability under the effect of underground water.
