勘察方法在山区公路隧道选址中的运用

Application of Investigation Methods for the Site Selection of the Mountain Tunnel

山区隧道常遇到地层岩性多变、地质构造和水文地质条件复杂等问题,选择工程地质条件良好的隧址,是控制隧道工程造价的关键,也是防控隧道工程风险最好的方法。本文研究了工程地质条件及其勘察手段对福建白土岩隧道选址优化中的作用和应用方法,通过隧道位置调整,大大降低了工程造价。

Mountain tunnel often faces some troubles, including much changeable stratigraphic lithology, complex geological structure conditions and complex hydrogeology condition. Some position with good engineering geological conditions should priority selected as the tunnel site, which obviously is the key to control of tunnel engineering cost and tunnel engineering risk. The application of investigation methods in site selection for mountain tunnel was in-depth studied. Through the adjustment of tunnel site, the engineering project cost is greatly reduced.
