Design and monitoring analysis of foundation pit support for sewage treatment plant

Taking the foundation pit supporting project of a sewage treatment plant in Changchun as an example, using BIM technology, the geological conditions of the construction site, the hydrological environment, and the distribution of surrounding buildings and other information are gathered, and the design scheme of foundation pit support is formulated. At the same time, the displacement of pile top and pile body in the construction is monitored in real time, and Midas GTS NX software is used for numerical simulation analysis and verification. The comparative analysis shows that the use of pile row prestressed anchor cable can effectively limit the lateral movement of foundation pit and reduce the influence of the foundation pit excavation on the surrounding buildings, which can provide effective reference for similar projects in the future.
