In the construction of deep foundation pits in soft soil areas, over-excavation of foundation pits and failure to set up support in a timely manner often occur. Due to the creep properties of soft soil, the envelope structure will be sharply deformed and cause engineering accidents. With the secondary development program of the elastic-viscose-plastic constructive model, simulate the conditions of normal construction and over-excavation of foundation pit in Soft clay area, analyze the time change regulation of retaining structures and safety state of foundation pit, in order to achieve effective control of the deformation and protect the buildings adjacent to foundation pit.
