摘　　要：本文以济南通信枢纽楼基坑工程为背景,分析了基坑工程的特点,并提出了具体的基坑和挡土墙支护方案。结果表明:基坑周边环境和管线复杂,应确保周边管线与支护结构无冲突;基坑侧壁主要由黏性土介质组成;基坑划分为6个支护单元,采用自然放坡及桩锚支护结构;挡土墙采用悬臂桩或悬臂式支护结构,分段施工;设置挡水墙、排水沟和集水坑等,保障工程排水畅通。Take the foundation pit engineering of Jinan communication hub building as an example,the characteristics of foundation pit engineering were analyzed,and the specific foundation pit and retaining wall support schemes were put forward.The results showed that surrounding environment and pipelines of the foundation pit were complex,and there should be no conflict between the surrounding pipelines and the supporting structure.Sidewall of the foundation pit was mainly composed of cohesive soil medium.The foundation pit was divided into 6 support units,using natural slope and pile-anchor support structure,the retaining wall adopted cantilever pile or cantilever support structure and was constructed in sections.Water retaining wall,drainage ditch,and sump should be set to ensure smooth drainage of the project.
