摘要
结合厦门市某海湾场地深大基坑支护工程设计实例,介绍了组合支护体系在海湾场地深大基坑支护工程中的应用。通过对基坑周边环境及地下室结构的分析,并充分考虑海湾场地岩土工程条件的复杂性,探讨了对基坑采用多种支护型式的组合支护体系进行支护的方法。基坑监测数据成果表明,该组合支护体系充分发挥了各类型支护结构的优势,取得了较好的预期效果。该支护体系极大地缩短了工期,降低了工程造价,带来了良好的社会效益和经济效益,可为海湾场地类似工程的基坑支护设计和施工提供参考。
Based on the design example of a deep foundation pit support project in a coastal area in Xiamen, the application of combined support system in deep foundation pit support works in the coastal area is introduced. Through the analysis on the surrounding environment and the basement structure of the foundation pit, and taking full account of the complexity of the geotechnical engineering conditions in the coastal area, the supporting method of combined support system with multiple support types is adopted. The results from the foundation pit monitoring data show that the combined support system has fully played the advantages of all types of supporting structures and achieved good expected results. The support system greatly shortens the construction period, reduces the cost of the project, brings good social and economic benefits, and can provide the reference for the design and construction of the foundation pit support for the similar projects in coastal areas.
