基于小角法位移监测公式及最佳设站位置理论证明

Verification of Formula and Optimal Position Setting during Displacement Monitoring Based on Small-angle Method

小角法测量基坑位移是基坑监测常用的方法之一。本文从基坑监测工作最常遇到的实际情况出发,研究了在位移点上设站观测的情况,并推导了相应的计算公式,同时从理论上证明了位移点设站情况下的最佳设站位置。

The small-angle method is one of the most common way for foundation pit displacement monitoring. In this paper, the condition of setting station on the displacement point is discussed. The correlative formulas are derived. Meanwhile, the optimal position of displacement-monitored point is proved in theory.
