摘　　要：研究目的:本研究旨在提高超前地质预报的精度和加快隧道施工进度,准确地预报出隧道掘进前方不良地质体的规模与位置,在施工中最大程度地减少工程投入和人员伤亡,同时也为今后隧道的超前地质预报提供有意义的借鉴。研究结论:得到一个精度高的预报结果需要满足以下条件:(1)在丰富的地质知识基础上需要对隧道所在地的地质构造及不良地质体进行现场地质调研,在此基础上应用各种物探方法进行定量预报和相互验证。利用物探方法探测时,首先要得到准确的现场探测数据。(2)在数据处理过程中需要处理人员有丰富的物探知识,能够正确确定各种参数的数值。(3)解译时要求解译人员有丰富的地质知识能够消除物探结果的多解性。Research purposes： The purposes are to improve the accuracy of geological prediction in advance, speed up the construction process of the tunnel, accurately predict the scale and position of unfavorable geological body ahead the place of tunneling, reduce the construction investment and person＇s death and injury during the construction and provide the reference to the similar works in future. Research conclusions： There must be the following requirements for getting the accurate results of geological prediction ： （ 1 ） The geological survey and investigation should be done on the site for geological structure and unfavorable geological body carefully, the quantitative prediction should be given with all prospecting methods and they should be verified each other. First of all, the accurate site surveyed data should be obtained when the prospecting method is used to survey. （2） The person for data processing should have the rich knowledge on the prospecting to correctly identify all numerical values of the parameters during the data processing. （3） The interpreter should eliminate the multi - interpreter of the prospecting result with rich geological knowledge when doing interpretation.
