【摘要】 在深基坑日益普及的今天,对基坑稳定性的监测要求也越来越高,高效快捷地完成基坑水平位移监测成为研究的重要问题。本文主要介绍了常用的4种基坑水平位移监测的方法,并对轴线法、小角法、极坐标法、自由设站法进行精度分析,当提高精度的措施在施工场地受限时,采用极坐标法结合自由设站的方法不仅计算简单、操作方便,而且能满足较高的精度要求。更多还原

【Abstract】 Nowadays,with the popularization of deep foundation pit,the requirements for monitoring the stability of foundation pit are higher and higher. It is an important problem to complete the monitoring of horizontal displacement of foundation pit efficiently and quickly. This paper mainly discusses four types of commonly used horizontal displacement monitoring methods of foundation pit,and analyzes the accuracy of axis method,small angle method,polar coordinate method and free station setting method,and gives the measures to improve the accuracy. When the construction space is limited,the polar coordinate method combined with free station setting method is not only simple in calculation and convenient in operation,but also can meet the higher accuracy requirements.更多还原
