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.
Based on the current lack of in-depth and systematic research on the prediction of karst fissure water at home and abroad, the accuracy and accuracy of the karst fissure water are not high at all, and the research on the new method obviously lags behind that of the engineering needs. Considering the merits of common methods, A new effective method for comprehensive prediction of karst fissure water is proposed.After summarizing the advanced geological prediction methods commonly used in tunnel engineering at home and abroad, based on the advantages of various forecast methods, according to the scientific process, Fissure water comprehensive prediction method, and finally combined with engineering examples of the front face of the gushing water disaster has been successfully forecasting and warning.Practice has proved that the comprehensive forecasting method has a high systematicness and efficiency, so that the prediction of karst fissure water is accurate Greatly improve the quality and accuracy, and make a reasonable assessment of the risk of water inrush disaster, which is worthy of promotion.
