| 摘 要： | 以实际工程为背景，介绍大型结构物的地基沉降变形的分析方法，分别采用室内回弹试验，野外平板载荷试验和堆载试验，综合确定土体的再压缩模量；采用等刚度法确定换填基础模量；采用《建筑地基基础设计规范》方法计算压缩层厚度；分别采用单向和双向施工方法，并同时考虑结构刚度，管段的相互影响，利用有限元方法对沉管的沉降差进行分析，计算，获得了沉管地基在不同施工阶段的变形量，结果与实测值较吻合，该方法适用于大型沉基坑内结构物地基的变形计算。 |
| 关 键 词： | 深基坑 地基 最终沉降量 再压缩模量 土体模量 |

| Abstract: | Based on practical project the analysis method of the deformation of foundation of large construction was introduced. The synthesized reload modulus was confirmed by resilience test, plate loading test, and large scale bearing test. The replacement foundation modulus was ensured by the method of equivalent-stiffness. Compression thickness was calculated with the method of criterion. Settlement differences in one directional construction and two directional construction were calculated by finite element method in which the stiffness of structure and mutual influence of tube segments were taken into account, and the results were fit for the measured values. The method can be applied to calculate foundation settlement in large deep foundation pit. |
| Keywords: | deep foundation pit final settlement of subgrade modulus of recompression |
