建筑基坑工程监测问题的探讨

Discussion on Monitoring of Building Excavation Engineering

基于工程实际需要,针对现行《建筑基坑工程监测技术规范》中的监测项目选择,监测点布置、监测频率确定以及监测报警值设置进行探讨,提出可适当降低基坑工程监测中土压力、孔隙水压力、地下水位及坑底隆起等监测项目的要求,并结合工程重要性调整监测频率、监测点布置和监测报警值。

Based on the engineering project requirements, the selection of monitoring, the arrangement monitoring -Spot and the determination of monitoring frequency by Technical Code for Monitoring of Building Foundation Pit Engineering are discussed. IT is suggested that the requirements on the monitoring of earth pressure, pore pressure, groundwater level and upheaval in the bottom could be reduced. The monitoring frequencies, setting of monitoring points and monitoring arrangement alarm value could be adjustment according to the importance of the project.
