隧道导线网测量误差对贯通误差影响值的严密估算方法

THE ESTIIMATING METHOD OF TUNNELING ACCURACY CAUSED BY SURVEYING ERRORS OF TRAVERSE NETWORK

本文探讨隧道导线网间接平差模型及精度估算方法,提出了导线网测量误差对隧道贯通误差影响值的严密估算方法,对准确地估计贯通误差及进行导线网的优化设计,都有一定的参考作用。

Based on the adjustment of indirect oboservation in traverse network of tunnel, this paper investigates andstudies the adjustment models and methods of estimating accuracy. It is proposed to estimate rigorously.Theaccuracy of tunneling caused by serveying errors af traverse network. These ressarches are probably helpful toestimate correctly the accuracy of tunneling and optimal design of the traverse network.
