摘要
The function of shallow groundwater injection to control the subsidence of the foundation pit is investigated to adopt sub-loading cam-clay model associating with the flow equations.For example,the subsidence or rebound data due to the dewatering and excavation of the Huaihai Middle Road No.3 site foundation pit close to Shanghai Metro Line No.1 are simulated with the soil-groundwater fully coupled calculated model.The calculated results are similar with the actual data and can reflect the strain subsidence behaviors of foundation pit excavation and dewatering.The method is used as reference for groundwater injection of foundation pit construction to reduce subsidence.
