- At the last , on the base of that , the author builds up 2 - d model ( modflow ) to simulate numerical value of surrounding underground water changes by tunnel water invasion , researches the effects on surrounding underground water system for tunnel drainage by desiccation , forecasts the restoring cases after the exclusion of water , at the same , analyzes the influences in underground water level and surface collapse by tunnel excavating
并且在此基础上建立modflow二维模型对隧道涌水引起周围地下水变化进行数值模拟，研究隧道疏干排水对周围地下水系统影响，进行模拟并预测堵水成功后水位的恢复情况，最后分析隧道对周围地下水位以及引起的地面塌陷的影响。 - First , on the base of investigating geleshan geologic environments , the author carefully analyzes them , studies their water storage structure , discusses the relationship of underground water dynamic changes and tunnel drainage by desiccation ; secondly , the author makes the dynamic analysis , regression analysis , routine hydrochemistry analysis , isotope analysis , so draws to guan - yin gorge anticlire east and west slot ' s karst developing features , alternated conditions underground water and supplying drain ways ; thirdly , by stating the fissuring ' s surveying data , the author calculates the seeping tensor
作者在进行歌乐山地质环境调查的基础上，仔细分析了大量观测资料，研究其储水构造，掌握地下水动态变化与隧道施工涌水的关系，及补给受降雨的影响情况。对隧道周围的地下水进行动态分析、回归分析、常规水化学分析以及同位素分析，得出观音峡背斜东西翼槽谷的岩溶发育特征，及地下水的循环交替条件、补给排泄途径；统计分析裂隙测量数据，计算渗透张量。
