广东佛山某项目基坑支护方案的优选及应用

Foundation Excavation Supporting Scheme Selection and Application to a Project in Foshan Guangdong

以广东佛山某基坑项目为例,根据该项目的工程地质条件及周边环境情况,结合基坑的形状和开挖深度等特点对基坑的支护结构体系进行选型分析,最终选出最优的基坑支护方案。合理的施工顺序、严格的土方开挖和实时的动态监测使该基坑支护方案成功应用于实际工程中,并顺利回填至地表面,实现了项目综合效益最大化,可为类似工程提供参考借鉴。

With a project in Foshan as an example, the selection and optimization of the foundation excavation supporting scheme are introduced in this paper, where the geological conditions and surrounding environment of the site are considered and the shape and the depth of the foundation excavation are systematically analyzed. The combination of reasonable construction sequence, strict earth excavation and real-time dynamic monitoring contributes to the successful application of such optimized scheme to to the actual project and backfilling to the ground surface is also finished so far. The selection and application processes have achieved the comprehensive benefit maximization of the project, which can provide reference for similar projects.
