某商业中心深基坑变形监测与分析

Monitoring and Analysis of a Deep Foundation Excavation

软土地区深基坑挖直是岩土工程领域的重点研究内容之。为确保基坑施工安全,对深基坑施工变形监测是信息化施工的重要内容。以宁波某深基坑工程为例,根据确定的监测方案及取得的数据,对支护结构的水平位移、深层水平位移、周边土体水平位移和沉降变化规律进行分析。由监测结果可知,该基坑工程支护结构的基坑变形控制设计方案合理。

Technology of deep foundation excavation in soft soil area is the one of the key research contents in project fields. In order to insure the safety of the deep foundation excavation,deformation monitoring on deep foundation excavation is an important content of information construction. Taking a deep foundation excavation project in Ningbo as an example,according to the analysis of certain monitoring scheme and the obtained data,the change rules of horizontal displacement,deep horizontal displacement,sedimentation and horizontal displacement of each monitoring point on the surrounding ground surface are analyzed in the excavating process. The monitoring results confirm the deformation control design of the supporting structure is reasonable.
