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
作者在進行歌樂山地質環境調查的基礎上，仔細分析了大量觀測資料，研究其儲水構造，掌握地下水動態變化與隧道施工涌水的關系，及補給受降雨的影響情況。對隧道周圍的地下水進行動態分析、回歸分析、常規水化學分析以及同位素分析，得出觀音峽背斜東西翼槽谷的巖溶發育特徵，及地下水的循環交替條件、補給排泄途徑；統計分析裂隙測量數據，計算滲透張量。 -
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
並且在此基礎上建立modflow二維模型對隧道涌水引起周圍地下水變化進行數值模擬，研究隧道疏干排水對周圍地下水系統影響，進行模擬並預測堵水成功后水位的恢復情況，最後分析隧道對周圍地下水位以及引起的地面塌陷的影響。
