摘　　要：可溶岩与侵蚀性地下水相互作用的过程将导致岩溶发育,地下水溶蚀作用对可溶岩原始结构面的改造强度影响其发育程度。登楼山深埋特长隧道可溶岩出露岩溶发育特征受控地层岩性、地质构造、排泄基准面和后期的外营力地质改造作用影响较大,在研究区出露岩溶发育特征各异,岩溶类型既有裸露型岩溶也有覆盖型岩溶,还有埋藏型岩溶。地表裸露型岩溶主要以汇水洼地、漏斗、落水洞、石芽等岩溶形态为主,地下岩溶主要以溶孔、溶洞、地下暗河为主。岩溶发育主要受气候背景、地质条件、水文网等因素控制,当气候背景、地质条件相似时,水文网则是控制地下水循环和岩溶发育的主要因素,通常情况下,岩溶系统中发育的大型水平和垂直岩溶管道可以反映水文网的稳定和下切的过程。The interaction between soluble rock and erosive groundwater will lead to the development of karst.The development characteristics of karst exposed from soluble rock in Dengloushan deep buried super long tunnel are greatly influenced by controlled stratum lithology,geological structure,discharge datum level and later external geological transformation.The development characteristics of karst exposed in the study area are different,including exposed karst,overburden karst and buried karst.The surface exposed karst mainly consists of catchment depressions,funnels,water caves and stone buds,while the underground karst mainly consists of dissolved pores,karst caves and underground rivers.Karst development is mainly affected by climate factors such as background,geological conditions,hydrologic network control,when the climate background,the similar geological conditions,hydrologic network is to control the groundwater circulation and the main factors of karst development,under normal circumstances,karst system in the development of large horizontal and vertical karst pipe can reflect the stability of the hydrologic network and incised.
