摘　　要：城市基础设施建设离不开基坑开挖工程,而科学合理的基坑支护结构设计和精细化的施工技术是保证工程质量安全的关键。研究介绍了基坑支护的作用及常用支护结构类型,着重分析了土钉墙、钻孔灌注桩和地锚等支护结构的设计方法及优化措施,并对相应的施工工艺进行了阐述。并通过典型工程案例,剖析了支护结构设计和施工中的问题,提出了改进对策,并强调了设计、施工各环节的质量控制和监测的重要性。The construction of urban infrastructure is inseparable from the excavation of foundation pit,and the scientific and reasonable design of foundation pit supporting structure and fine construction technology are the key to ensure the quality and safety of the project.This paper introduces the function of foundation pit support and the types of common supporting structures,emphatically analyzes the design methods and optimization measures of soil nailing wall,bored pile and ground anchor,and expounds the corresponding construction technology.Through typical engineering cases,the problems in the design and construction of support structure are analyzed,and the improvement countermeasures are put forward.The importance of quality control and monitoring in every link of design and construction is emphasized.
