某大楼深基坑监测及其成果分析

Monitoring and Results Analysis of Deep Foundation Pit Engineering of a Building

根据某大楼深基坑支护结构的支护特点及其周边环境情况,制定了切实可行的监测方案。重点对支护工程顶部垂直和水平位移、周边地表及建筑物沉降、支护结构侧壁水平位移、地下管线沉降、地下水位进行监测,并对监测数据进行整理分析。监测结果为围护结构体系和基坑环境安全提供了全面、准确、及时的监测信息,为现场的施工安全以及合理的组织施工提供了可靠依据。

According to the characteristics of supporting structure and the surrounding environment conditions of deep foundation pit engineering of the building, a practical monitoring program is developed. Vertical and horizontal displacement of the top of support engineering, the settlement of surrounding ground and building, the horizontal displacement of sidewalls of supporting structure, settlement of underground pipeline, and groundwater level were monitored mainly, and the monitoring data was analyzed. The monitoring results provide comprehensive, accurate and timely monitoring information for the containment system and environmental security of deep foundation pit engineering, and provide the reliable basis for the security of construction site and the reasonable construction organization.
