摘　　要：研究目的:隧道施工超前地质预报的可靠性一直困扰着工程技术人员,预报结果的准确与否,预报信息的精准程度对隧道施工非常关键。如果能正确认识现有预报方法与技术存在的问题,将有利于不断提高预报的技术水平。本文针对影响超前地质预报可靠性的几个主要影响因素展开论述,分别从预报方法、解释判译、空间定位、波速确定及探测能力等方面指出目前常见预报方法存在的问题与局限性。研究结论:(1)目前的大多数预报方法都具有局限性,需正确认识和分析预报结果;(2)复杂地质条件下隧道施工超前地质预报应进行综合预报,组合多种方法,相互印证与补充;(3)综合参数和空间预报理论、方法与技术可提高预报的可靠性和精度。Research purposes： The reliability of the advanced geological forecasting for tunnel construction has puzzled engineering technical personnel all the time, and the accuracies of the forecasting result and the forecasting data are crucial to the tunnel construction. If the problems existed in the current forecasting methods and technologies are realized correctly, it will favour continuous improving the forecasting technical level. This paper discusses the main influence factors on the reliability of the advanced geological forecasting for tunnel construction and points out the problems and limitations existed in the current forecasting methods in the areas of the forecasting method, interpretation, space orientation, wave velocity orientation and survey capacity. Research conclusions： （ 1 ） Most of forecasting methods have limitations at present, so it is necessary to correctly understand and analyze the forecasting result. （2） Under the complicated geological condition, the comprehensively advanced geological forecasting should be conducted with many methods to verify and supplement them each other. （3） The forecasting reliability and precision can be enhanced by using the synthesized parameterand and space forecasting theory, method and technology.
