| 中文摘要:介绍荆州市恒大翡翠华庭项目基坑支护体系设计方案选型思路。本项目地质条件差，周边环境极为复杂，通过弹性抗力法计算模型，运用天汉软件对支护结构内力和变形进行计算，以及基坑抗隆起、抗倾覆、整体稳定性等验算，选择采用SMW工法。计算结果与基坑监测资料对比分析结果显示，应用SWM工法桩作为支护结构，达到设计合理、经济适用的效果，保证了基坑及周边建筑的安全。本工程是SWM工法桩在荆州市基坑支护工程中的首次应用，同时获得了显著的社会效益。 |

| Abstract:The approach to selection of the design of the foundation pit support system for a project in Jingzhou is introduced. The geological conditions of this project are poor and the surrounding environment is extremely complicated. The SMW method was adopted through calculation of the internal force and deformation of the support structure with Tianhan Software based the elastic resistance calculation model, and verification of the foundation pit anti-uplift, anti-overturning, overall stability, etc. Comparison of the calculation results with the foundation pit monitoring data showed that use of SWM piles as the support structure provides a reasonable design and economics, and ensure the safety of the foundation pit and surrounding buildings. It is the first application of the SWM piles used in the Jingzhou foundation pit support project, and it has obtained significant social benefits. |
