| 摘 要： | 在综合考虑前人对基坑变形研究的基础上，分析其中存在的不足，提出了按正态分布并结合三角形分布计算由支护结构变形引起的地表沉降值的公式，同时分析了由水位变化所引起的地衣沉降，该方法将为开挖和降水过程中基坑边缘地面沉降值提供预测，为工程设计提供更切合实际的方案。

| Abstract: | Based on the former research on the excavation pit's deformation, the author provides a formula calculating the surface settlement caused by the deformation of supporting structure. And this formula is formed on the basis of normal distribution and triangular distribution. In addition, the surface settlement caused by the descent of water level is analyzed. This method can estimate the settlement at the edge of the excavation pit during the process of excavating and dewatering, and can provide more reasonable design scheme for the project. |
