【摘要】 西南山区喀斯特特征显著,在修建山岭隧道过程中,岩溶、暗河给隧道施工带来了不利因素,不仅施工安全会受到影响,而且还会增加额外的治理费用。通过现场地质勘查和地表冲沟连通实验,对马嘴隧道暗河特征和形成原因进行分析,根据其涌水量小,埋深浅和暗河洞室小的特点,制定了适合现场的四组处治方案。最后,利用突变级数的原理,从安全、技术和经济3个方面综合考虑,用极差变换法对各个可量化指标进行初始模糊隶属函数值赋值,得到暗河段各个处治方案的综合评价指标,选取了最优方案。更多还原

【Abstract】 The southwest mountain area of Karst is a remarkable characteristic in the process of building mountain tunnel; karst and underground river have brought unfavorable factors to the tunnel construction, not only the construction safety will be affected,but also it will increase the cost of treatment of extra. Through field geological survey and ground gully connected to the Mazui underground river tunnel experiment,characteristics and the causes were analyzed; according to the water inflow of small,shallow underground cavern and the characteristics of small,four groups of treatment scheme for onsite had been Carried up. Finally,using the principle of catastrophe progression and from the three aspects of safety,technical and economic,it was thought that the initial value of each fuzzy membership function could be obtained by range transformation method to estimate the comprehensive evaluation index of each treatment scheme of underground river section and select the optimal scheme. Specific scheme was used to construct a drain sump on the left side of the left line and dark river could be flow outside tunnel through the center ditch.更多还原
