新型组合支护体系在回填土基坑工程中的应用研究
摘要:结合一种新型组合支护体系在北京市某深基坑工程中的应用,分析介绍了该体系的支护形式及结构特点。对该支护体系进行了理论计算、数值模拟和现场监测分析,结果表明,该支护体系成功解决了人工填土深厚、场地空间狭小、周边环境复杂等深基坑支护的技术难题,可以有效控制基坑变形,缩短施工工期,节约工程成本,保证基坑工程安全使用,为同类工程提供有效的借鉴经验。
Abstract:Combined with the application a new type of composite supporting system in a deep excavation engineering in Beijing, the supporting form and structure features of the system are analyzed and introduced. Theoretical calculation, numerical simulation and field monitoring analysis of the support system are carried out. The result shows that the support system successfully solves the technical difficulties of deep foundation pit, such as deep artificial fill, small space and complicated surrounding environment. It can effectively control the deformation of the foundation pit, shorten the construction period, save the cost of the project, ensure the safe use of the foundation pit engineering, and provide an effective reference experience for similar projects.
