深基坑开挖周边地面最大沉降预估

Maximum Sedimentation Predict of Circumjacent Ground of Deep Footing Groove Excavated

文章简述了超限差异沉降是引起建筑物损伤的主要原因之一,对开挖卸荷引起周边环境最大沉降量预估方法进行了研究,结合工程实例,根据某深基坑工程的深层位移监测和地面变形的观测资料,定性地分析了开挖卸荷引起基坑周边环境的最大沉降量预估方法。

This text depicts that the excessive differential settlement is one of the reasons which will cause the building damages, and the maximum sedimentation predict method of circumjacent circumstance by excavating and down loading, and the experience in project example. Based on the deep layer displacement observation and ground reformation of a deep footing groove project, the maximum sedimentation predict method of circumjacent circumstance by digging and down loading is qualitative analyzed.
