摘要: “桩墙合一”技术考虑基坑围护桩与地下室外墙共同作用作为正常使用阶段的地下室侧壁挡土结构，可减薄地下室外墙的厚度、减少基坑面积，有利于节约工程造价，节能降耗，具有良好的社会经济效益。通过工程应用考虑了“桩墙合一”技术的防水、传力构造等，并通过基坑开挖阶段、正常使用阶段、抗震等多工况进行“桩墙合一”的强度与耐久性设计计算，可作为今后类似工程设计的参考。

Abstract: Used as the lateral retaining structure during the regular service stage considering the combination of support piles and basement external walls, the technique of the unity of support piles and basement external walls can reduce the thickness of basement external walls and the excavation area, so it has good economic and social performances by saving the project cost. Through project application, the waterproof design and the load transfer slab are considered, and the strength and durability design are calculated under various conditions of excavation stage, regular service stage and earthquake stage. These outcomes can be referenced in future other similar projects.
