| 摘 要： | 安六铁路六枝至茨冲段线路以隧道为主,岩溶及岩溶水问题较为突出。为合理确定线路平面位置及走行高程,降低隧道(涌)突水、突泥等地质灾害,开展了区域地质调绘及水文地质专题研究。文章分析了隧址区水文地质条件、岩溶发育特征规律及暗河系统补给、径流、排泄等地质问题,对线路方案进行比选,提出沿长江水系与珠江水系分水岭的最优线路方案,可为同类项目提供参考。

| Abstract: | Tunnel is the main part from Liuzhi to Cichong section of Anliu Railway,the problems of karst and karst water are prominent.In order to reasonably determine the line plane position and height,to reduce tunnel(surge)water inrush,mud and other geological disasters,the regional geological mapping and hydrogeological studies are carried out.The paper analyzes the hydrogeological conditions,karst development characteristics and the problems of supply,runoff and discharge in the underground river system,compares and selects the route plans,proposes the optimal route scheme along the watershed between the Yangtze river system and the pearl river system,provides reference for similar projects. |
