Application of dense surface modeling technology in displacement monitoring of deep foundation pit

针对传统监测技术在城市深基坑位移监测中存在监测难度高、时间长、劳动量大等问题,提出采用密集曲面建模技术进行监测。基于密集曲面建模原理,结合PMS软件及硬件设备,对该技术监测位移的精度进行了分析。分析结果与工程实践表明,密集曲面建模技术应用于基坑位移监测,可快速、准确反映深基坑施工所引起的周边土体变形。

According to the problems in the application of traditional monitoring technology in displacement monitoring in deep foundation pit, such as difficult monitoring, long monitoring time and large labor intensity, the dense surface modeling technology is presented. Based on the principle of dense surface modeling, the accuracy of monitoring displacement was analyzed in combi-nation with PMS software and hardware devices. The engineering practice and analysis results verify that the dense surface model-ing technology can be applied in the displacement monitoring of deep foundation pit, which can quickly and accurately reflect the deformation of soil body induced by surrounding foundation pit excavation.
