Design and Application of SMW Method in the Supporting Sistem
Abstract:Introduce the idea of selecting the design scheme of the foundation pit supporting system of the the JingZhou Evergrande Emerald Huating Project . The geological conditions of this project are poor and the surrounding environment is extremely complicated. The elastic resistance method is used to calculate the model, and the internal force and deformation of the supporting structure are analyzed using Tianhan software The calculation, as well as the calculation of the foundation pit anti-uplift, anti-overturning, overall stability, etc., chose to use the SMW construction method, and the later analysis and comparison of the calculation results with the foundation pit monitoring data showed that the use of SWM construction method as a supporting structure to achieve a reasonable design and economic The applicable effect guarantees the safety of the foundation pit and surrounding buildings. This project is the first application of the SWM construction method pile in the Jingzhou foundation pit support project, and it has obtained significant social benefits.
