| 摘 要： | 对杭州及上海软土地区十几个成功基坑工程的围护体最大侧向变形、最大侧向变形位置、邻近建筑物的沉降以及变形的时间效应等进行了分析研究和总结,并与前人的研究成果进行了比较。文中还根据建筑物沉降产生机理及工程实测资料提出了一种考虑邻近建筑物存在的地表沉陷估算方法。最后得出了几个对工程界有一定参考价值的结论

| Abstract: | The magnitude and location of maximum lateral wall deflection,settlement of adjacent existing buildings,and time effect of deformation of more than ten excavation cases on soft clay in Hangzhou and Shanghai are analyzed in this paper,and the results are compared with that given before.Then an empirical settlement formula is provided based on the settlement mechanism of adjacent existing building and field observation data. Finally,some referable conclusions are obtained. |

| Keywords: | excavation deformation settlement soft clay time effect |
