    Abstract
  • The divided pit excavation and excavation process of foundation pit group engineering are complex, and the environmental impact superimposed effect is significant. The above problems cannot be analyzed by the standard design and calculation method. Taking a project in a soft soil area of Shanghai as the background, a variety of conceptual models were established to analyze the impact of different divided pit excavation of large-area foundation pits on the surrounding environment, and analyze the superimposed impact of different excavation sequences of adjacent foundation pits on the environment, and guide the overall zoning and working condition design of foundation pit group projects. The monitoring data showed that the impact of the project implementation on the environment is generally controllable, and the key strengthening areas have little impact on the sensitive protection objects such as the operating subway. The relevant analysis results and design countermeasures can be used as a reference for similar projects.
