摘要
通过分析乌池坝隧道岩溶发育特征,并结合相关因素,得到以下结论:(1)岩溶发育在垂直方向上具有明显的强弱交替分布的特点;而在水平方向上两种岩性的交界线附近岩溶较为发育;(2)地下水和可溶性岩层是岩溶发育的必要条件,可溶性岩层存在地下水时,岩溶发育更强烈;(3)岩溶发育程度的大小由当地的地层岩性、地质构造、发育深度及气候等条件决定。
After analysis on the karst development law of Wuchiba Tunnel and relevant factors, this paper reached the following conclusions： （1） strong and weak karst development alternated obviously along the vertical direction and the karst near strong and weak karst development border develops faster along the horizontal direction; （2） groundwater and dissoluble stratum are necessary conditions for karst development and karst develops faster when there is groundwater in the dissoluble stratum; （3） the karst development degree is determined by local conditions, such as stratum lithology, geological condition, development depth and climate, etc.
