重庆走马岭隧道开挖中岩溶涌水灾害是一个突出问题.为预测隧道发生涌突水灾害的可能性,以隧址区泉水样及隧道内涌水样中的7种常见离子为研究对象,采用模糊聚类分析方法确定相应的模糊等价矩阵R°=(rij°)n×n,将所取15个水化学样进行合理分类.本次模糊聚类分析表现出很好的相关性,结合地质条件对其分类结果进行解释,准确地划分出隧址区地下水微系统,初步预测突发性岩溶涌突水灾害发生可能性小.
The karst gushing disaster in the excavation of the Kuomaling Tunnel in Chongqing is a prominent issue.In order to predict the possibility of water inrush from the tunnel, seven kinds of common ions in the tunnel-like spring water samples and gushing water samples in the tunnel are taken as research objects, Fuzzy clustering analysis method to determine the corresponding fuzzy equivalent matrix R ° = (rij °) n × n, the 15 water samples taken reasonable classification of the fuzzy clustering analysis showed a good correlation, combined Geological conditions to interpret the results of its classification, and accurately distinguish the groundwater micro-system of the tunnel area, preliminary prediction of sudden karst intrusion water hit possibility is small.
