基于重要风险源的深基坑监测测点优化布置

The Optimal Design of Measurement Point Layout for Monitoring of Foundation Pit Engineering Based on Important Risk Source

根据风险评估理论,重点讨论风险评估与测点优化之间的关系,提出了基于重要风险源的测点优化布置方法,结合近年笔者参与的30多项基坑监测工程的现场经验和数据分析,详细论述了测点优化布置方法在基坑监测工程中的实用性和有效性,总结出其布置的相关准则,对实际工程有一定的指导意义。

Starting from the basic theory of risk assessment,the paper draws forth the intrinsic link between risk assessment and the optimal design of measurement point layout,proposes measurement point layout methods based on risk-based Engineering major source.combined with the author's experience and the results of monitoring of thirty actual foundation pit engineerings in recent years,the paper verifies the practicality and effectiveness of the methods,and summarizes the corresponding criterion,which makes up the existing norms and could be used to guide the actual construction effectively.
