模糊数学优化关键孔注浆方案在处治复杂岩溶裂隙中的应用研究

摘要

Under complicated geological conditions of karst fissure water damage to tunnel and underground engineering poses a great threat, the treatment of karst fissure is particularly important. Was adopted for the first time key hole grouting method applied in tun-nel engineering, control engineering with the Qiyueshan Tunnel of Liwan highway, through the geological survey and geological radar de-tection, and the first to use fuzzy mathematics to construct the optimizing selection of grouting hole model. For the first time, the key hole grouting method, through scientific and rational optimization of the key hole, in Qiyueshan tunnel is completed the task of grouting for stopping up water, and achieved good results. Using the fuzzy mathematics analysis method to carry on the key hole optimization, through the fuzzy mathematics analytic hierarchy process, establishes the mathematical model, the very good solution in the key hole choice ques-tion;the model is very good in the project key hole to choose some qualitative factors to carry on the transformation to be able to use the mathematics to express, more intuitive and effective evaluation of key hole quality.%复杂地质条件下岩溶裂隙水害给隧道等地下工程带来巨大威胁，处治岩溶裂隙带来的问题尤为重要。首次采用关键孔注浆方法在隧道工程中应用，结合利万高速齐岳山隧道控制工程，通过地质勘测和地质雷达探测，并首次采用模糊数学构建模型优化注浆孔选择。首次采用关键孔注浆方法，通过科学合理的优化关键孔，在齐岳山隧道工程中很好的完成了注浆堵水的任务，取得了较好的效果。采用模糊数学分析法进行关键孔的优选，通过模糊数学的层次分析法，建立了数学模型，很好的解决了在关键孔的选择难题；模型很好的将在工程中关键孔选择一些定性的因素进行转化成可用数学来表示，更加直观有效的评价关键孔的质量。
