| 摘 要： | 研究目的:基坑开挖引起的土体移动会使得周边建(构)筑物发生不同程度的附加变形,并对环境造成影响.本文通过杭州火车东站通道基坑现场实测数据与理论计算数据的对比,分析了SMW工法桩加预应力锚索的支护体系引起远坑壁处产生过大竖向沉降的原因,希望能为类似支护设计选型、施工提供指导意见.研究结论:基坑隆起、围护墙位移、锚索施工、...

| Abstract: | Research purposes: The soil movement caused by the excavation of foundation pit can produce the additional deformation of the surrounding building and structure in varying degrees and influence the environment.In this paper,based on the comparison of the actually monitored data with theoretical calculation data of the passage foundation pit of Hangzhou Railway Station,the analyses of the reasons for big vertical ground settlement of the far pit wall caused by SMW process pile and anchor support system are m... |
