| 摘 要： | 某地铁车站深基坑施工过程中,基坑北侧建筑物产生了明显的不均匀沉降,且整体沉降较大。对不同施工阶段基坑临近建筑物沉降进行监测,分析引起建筑物沉降的原因,介绍了施工过程中应的一些应对措施。通过监测分析发现:建筑物沉降是各种综合因素引起的,施工中各个环节都应该予以控制;高压旋喷桩施工对建筑物沉降影响较大;基坑开挖过程中应严格控制地下连续墙变形,及时附加预应轴力,合理控制基坑及建筑物周边降水量。

| Abstract: | The construction of some metro foundation excavation causes differential settlement at the north adjacent building,and the settlement reach rather high level.By monitoring the settlement at different stages,the author analyzes the causes of settlement,and introduces some solutions.Through the monitoring and analysis,it proves that the building settlement is caused by many linking factors,so all the stages need strictly attention.Moreover the construction of high pressure jet grouting piles has great influen... |
