| 摘 要： | 本文根据全站仪非接触测量原理，分析了隧洞测点位移量测的三维误差计算式。随后对全站仪位移量测的误差精度进行了分析，得到了满足反演计算要求的量测误差判别式，并提出全站仪位移量测的可行性判别方法。最后通过算例给出了判定实际工程反演分析可行的设站及仪器的优选方式。分析结果认为目前全站仪的测量精度还只适用于洞室断面较大、总位移量较大的情况，对洞室反演计算的普遍适用还有一定距离。

| Abstract: | Based on the error transfer principle of measurement device the error of non-contact measured displacement by total station is analyzed and the formula for calculating the error is deduced. A diseriminant for determining the feasibility of using the measured displacement to back analyze the parameters of surrounding rock in tunnel is proposed. An example of application is given. |
