瓦窑坡隧道岩溶地质超前预报综合技术

瓦窑坡隧道施工地质条件非常复杂,存在岩溶、冲沟浅埋段和破碎带等不良地质现象。其中,岩溶是本隧道施工的最主要地质问题。根据隧道地质、地形条件及不良地质现象,隧址属构造剥蚀中低山区,地表溶蚀强烈,见多处岩溶漏斗,根据瓦窑坡隧道施工的特点,以地质法为基础,以TGP206地质超前预报系统为主要手段,结合地质雷达和钻探等地质超前预报综合技术,进行岩溶地质超前预报。开挖结果证明,瓦窑坡隧道综合地质超前预报技术的应用是基本成功的,值得在同类隧道施工地质预报中借鉴。

Synthetic Prediction Technology of Karst Geology in Wayaopo Tunnel

Geological conditions of Wayaopo tunnel are complex,including karst,shallow-buried gully,rupture zones and so on.Where Karst is the most principal geology problem.According to geology and topography condition and adverse geologic phenomena,it is predicted that Wayaopo tunnel site belongs to tectonic denudation mid-low mountains,where surface corrosion is growing,and many dolines are found.According to construction characteristic of Wayaopo tunnel,based on geology method,Karst geology is predicted with TGP20...
