| 摘 要： | 通过对基坑施工引发的工程性地面沉降进行影响因素分析,结合地质结构条件,划分了上海地区典型基坑模型,采用数值方法分析了不同基坑模型在不同围护结构变形模式和降水条件下引发地面沉降的基本规律,提出了不同类型基坑工程引发的地面沉降影响范围,并在基坑工程实例中得到了有效验证. |
| 关 键 词： | 基坑 工程性地面沉降 基坑模型 影响规律 变形模式 降水 |

| Abstract: | Based on analysis of impact factors of engineering land subsidence induced by foundation ditch construction,combined conditions of geological structure,typic pit model in Shanghai has been divided.The regularities of land subsidence induced by deformation of exterior-protected construction and pit precipitation were deeply researched using the numerical analysis method,and the impact range of engineering land subsidence of different typic foundation ditchs has been given.Finally case study of pit constructi... |
| Keywords: | foundation ditch engineering land subsidence pit model impact regularities deformation model precipitation |
