明挖地铁车站桩体位移测斜及钢支撑轴力的关系

摘要

介绍了桩体测斜仪与钢支撑及轴力频率读数仪的工作原理，针对明挖地铁车站基坑开挖过程中围护桩桩体测斜及钢支撑轴力的监测成果进行分析讨论，总结了桩体位移与钢支撑轴力之间的关系，对保证基坑的安全性具有重要意义。%This paper introduced the working principle of pile inclinometer and steel support and axial force frequency readout instrument,made analysis and discussion according to the monitoring results of envelope pile inclinometer and steel support axial force,summarized the relationship of pile displacement and steel support axial force,had important significance to ensure the safety of foundation pit excavation.
