温州某深基坑变形监测与成果分析

基坑开挖会引起基坑周围土体应力释放,可能引发周围建筑物基础或管线等的变形,严重的可能引发重大事故。基坑围护结构设计的安全程度与施工过程密切相关,必须系统地对基坑进行监控,及时获取基坑开挖过程中支护结构受力与变形信息,及时发现事故预兆。通过合理、有效地开展基坑边坡及其邻近建筑物变形监测,以满足信息化施工要求,从而达到安全预报、反馈设计、指导施工的目的。为此,结合某深基坑工程的变形监测简要介绍了基坑工程变形监测的项目、布置与观测方法,随后对变形监测结果进行了初步分析。

Deformation Monitoring and Results Analysis of a Deep Foundation Pit Engineering in Wenzhou

Excavation will cause stress of soil around the foundation release,may lead tothe deformation of surrounding buildings or pipelines in severe cases may lead to major accident Foundation pit design and construction of process safety is closely related to the systematic monitoring of the pit,timely botain of information of support structure force and deformation during pitexcavation,timely detection of incidents omen.Through reasonable and effective monitoring deformation of excavation slope and adjacent buildings to meet the construction requirements of information to achieve the safety prediction,feedback,designing and construction purposes.In this paper,combied with the monitoring of deformation of a deep excavation excavation deformation monitoring of the project,arrangements and methods of observation were outlined,and then on deformation monitoring results were preliminary analysed.
