【摘要】：为科学地选择隧道施工期间的地质预报方法,提出基于突变理论的隧道地质预报方法优选的突变级数法。首先,对隧道地质预报方法的评价目标进行层层分解;其次,将底层评价因素进行无量纲化、归一化处理;然后,运用不同突变模型的归一公式进行逐层计算,得到突变级数值,给出最优方案。利用该方法对紫金山隧道F2断层中岩溶涌水的5种预报方法进行比选,得出地质雷达法为最优方法。该方法可避免人为确定权重的主观性,且计算简单、可靠性高,优选结果更趋于实际。
[Abstract]:In order to scientifically select the geological forecast method during tunnel construction, the catastrophe series method of tunnel geological prediction method based on catastrophe theory is put forward. Firstly, the evaluation objective of tunnel geological forecast method is decomposed layer by layer. Secondly, the evaluation factors of the bottom layer are dimensionless and normalized. Then, by using the normalization formulas of different catastrophe models, the catastrophe order value is obtained, and the optimal scheme is given. The five prediction methods of karst water gushing in the F2 fault of Zijinshan Tunnel are compared and selected by using this method. It is concluded that the geological radar method is the best method, which can avoid the subjectivity of artificially determining the weight, and the calculation is simple, the reliability is high, and the optimal selection results tend to be more practical.
