摘要
以济南某基坑支护工程为例,针对现场面临的基坑开挖深度大、地质条件及周边环境复杂等因素影响,设计了以桩锚与复合土钉墙相结合的联合支护方式,并进行了现场施工及监测分析。现场施工及监测数据表明:采用桩锚与土钉墙联合支护方式,可有效控制基坑变形及周边建筑物变形,确保工程施工质量和安全,节约工程成本,缩短施工周期。桩锚与土钉墙联合支护是一种有效的基坑支护方式,可为复杂条件影响下的基坑设计及施工提供一定借鉴意义。
Taking a foundation pit supporting project in Jinan as an example, aiming at the problems of large excavation depth, geological conditions and complex surrounding environment in the site, the design of combined support with pile anchor and composite soil nailing wall way, and conducted on-site construction and monitoring analysis. The site construction and monitoring data show that the combined support of pile anchors and soil nailing walls can effectively control the deformation of the foundation pit and the deformation of the surrounding buildings, ensure the construction quality and safety, save the construction cost and shorten the construction period. The joint support of pile anchor and soil nailing wall is an effective foundation pit supporting method, which can provide reference for the design and construction of foundation pit under complex conditions.
