摘要
隧道工程测量是地下工程测量的重要组成部分,它是在隧道工程的规划、勘测设计、施工建造和运营管理的各个阶段进行的测量,对地下工程的施工起着关键性作用。同时复杂的地质环境也将对隧道施工产生决定性的影响。本文以包西铁路冒天山隧道为例,详细描述隧道施工中洞外控制测量、洞内平面控制、中线及高程的控制测量以及贯通误差的计算方法,最后探讨特殊地质条件下隧道施工的对策。
Tunnel engineering surveying is an important part of underground engineering surveying,it isthe surveying at planning,survey design,construction and operation management of the tunnel engineering,It plays a key role to the construction of underground engineering.At the same time,A complex geological environment will also be a decisive influence on the tunnel construction.This article is as a case of Mao Tian-shan Tunnel in Bao-xi Railway,detailed control survey outside hole,plane control inside the hole,the control survey of mid-line and elevation and the calculation method of breakthrough error of the tunnel construction.And finally discusses the countermeasures of tunnel construction under special geological conditions.
