深厚软土基坑测斜管埋设深度对比分析

Comparative Analysis of Buried Depth of Inclinometer Pipe in Deep and Thick Soft Soil Foundation Pit

为总结深厚软土基坑测斜管埋设不同深度的变形规律,文章以广东珠海横琴某深基坑监测数据为基础,通过对比各测斜监测点在不同深度曲线变形情况,发现测量深度与桩深越接近,测量结果中底端位移的稳定性越强。这种自下而上的测量资料整理方法,以底部为基准点,能更准确地反映位移情况,符合规范要求。

In order to summarize the deformation law of inclinometer pipe buried at different depths in deep and thick soft soil foundation pit,based on the monitoring data of a deep foundation pit in Hengqin,Zhuhai,Guangdong,by comparing the deformation of each inclinometer monitoring point at different depth curves,it is found that the closer the measurement depth is to the pile depth,the stronger the stability of the bottom displacement in the measurement results.This bottom-up measurement data sorting method,with the bottom as the reference point,can more accurately refl ect the displacement situation and meet the requirements of the specifi cation.
