综合超前地质预报方法在观音山隧道施工中的应用
|
摘要
大多数隧道开挖地质情况复杂,地质灾害时常发生,单一的地质预报方法往往不能够比较全面地提供隧道掌子面前方的地质情况信息,这样一来可能造成地质灾害的漏报和误报.所以必须根据隧道的地质情况,采用2种或2种以上的预报方法进行隧道施工地质超前预报,相互验证,提供较为全面的地质预报信息.综合分析观音山隧道地质条件,地质预报组采用以地质调查法为基础,综合地震波反射法法和地质雷达法,三者相结合的方法对观音山隧道施工进行地质超前预报,取得了良好的效果,为隧道开挖提供了科学的指导和依据.
Most tunnels always confront the complex geology, and geological disasters happen unexpectedly. The geological predicting method, if only adopting single predicting method, would not be providing the complete geology information of tunnel face in advance, which would lead to the information prospecting missed and even wrong information. So we must adopt at least two or even more methods, if possible, to predict the tunnel geology information under construction; comparing the information provided to sort out the fairly complete geological predicting information. Based on the analyzed tunnel geology information of Guanyinshan, the geological prospecting team adopted the geology researching as the start point, and took the method of TSP and the method of geological radar, to make the geological information predicting of the Guanyinshan Tunnel constructing. It has made good effects in construction and provided scientific guidance and practical base.
