【摘要】 基于目前国内外所进行的岩溶裂隙水预报缺乏深入系统的研究,普遍存在准确性和精度不高,而新方法的研究明显滞后于工程需要的问题.考虑将常用方法的优点加以综合,建立一种新的行之有效的岩溶裂隙水综合预报方法.在总结了国内外隧道工程界常用的超前地质预报方法,综合各种预报方法优点的基础上,按照科学的流程,提出并建立了针对岩溶裂隙水的综合预报方法,最后结合工程实例对掌子面前方的涌水灾害进行了成功地预报和预警.实践证明,综合预报法具有较高的系统性和工作效率,使岩溶裂隙水的预报准确性和精度大大提高,并可对涌水灾害风险进行合理的评价,是值得推广的方法.更多还原

【Abstract】 In the prediction of karst-fractured groundwater,thorough and systemic research is deficient,and there are problems that the accuracy and precision is low.Research on the new technique can not catch up with the engineering demand.For solving this problem,the advantages of the common methods were integrated,and a new integrative method feasible to karst-fractured groundwater prediction was established.First,the advanced geological forecasting methods used in tunnel construction were summarized.Then,based on the scientific process,the integrative advanced geological forecasting method for karst-fractured groundwater was established by comprehensive analysis on the advantages of all the prediction techniques.Finally,the water gush disaster was successfully forecast and earlywarning in the project example.With high systematicness and efficiency,the use of this integrative geological forecasting method makes the accuracy and precision of the prediction highly improved and gushing water disaster risk rationally evaluated,which is worthy to be generalized.更多还原
