佛山市某地区地面沉降成因分析及防治对策

Land Subsidence Cause Analysis and Control Countermeasures in a Certain Area of Foshan

东南沿海是我国地面沉降发育严重的地质灾害区,以佛山某地区为实验区,阐明了实验区地面沉降成因主要为基坑降水,论证了基坑工程活动与地面沉降的关联性,并相应采取防治措施从而控制地面沉降的深度发展。

The land subsidence in southeastern China coastal region developed severely.Taking a certain area of Foshan as the experimental area,this paper finds out that the mainly cause of ground subsidence is the foundation pit dewatering.At the same time demonstrates the correlation between foundation pit engineering activities and ground subsidence,and take corresponding prevention and control measures,so as to control of the ground subsidence depth development.
