引水隧洞复杂地质段地质超前预报综合评价

由于单一地质超前预报方法对复杂地质段预报的局限性,本文则主要通过地质编录法、瞬变电磁法、水平声波反射法三种方法的综合分析,避开各种方法局限性的影响,完成对复杂地质段的超前预报,同时成功预报一个次生断层以及该断层影响带宽度,并给施工提供合理建议,使得施工顺利进行。预报结果与实际开挖地质情况基本一致,取得了显著效果。因此,在面对复杂地质段时,应用地质编录法、瞬变电磁法、水平声波反射法综合评价地质情况,获取准确、可靠的地质超前预报结果,是一种高效、可行的组合方法之一。

Geological Prediction Evaluation of the Complex Geological Section of Diversion Tunnel

This paper analyzes the three methods of geological record,time domain electromagnetic methods(TEM) and Horizontal Sound Probing(HSP) to avoid the limitations from the methods so as to complete the complex geological predication and meanwhile predicts the secondary fault and the width influenced by the fault.This paper also provides some reasonable suggestions for the construction,so the work goes on very well.Therefore,it is efficient and acceptable to adopt the methods of the geological record,TEM and HSP...
