| 摘 要： | 鄂西南岩溶地区表层岩溶个体形态复杂多样,表层岩溶带发育与鄂西南地区岩溶地质环境条件及岩溶发育演变的历史过程密切相关.因此,通过野外地质调查与收集"沪蓉西"高速公路勘察资料.采用系统工程地质分析为主的方法,研究了表层岩溶带在不同的地质构造部位、地层岩性、地形地貌部位及深部岩溶水补径排区的发育强度及其变化规律.详细论述了表层岩溶带的空间发育强度.首次定量界定了该区表层岩溶带的最大发育深度为56.54m,最浅为4.5m,阐明了表层岩溶带从山顶、山脊到山脚、沟谷由弱到强的总体变化规律.

| Abstract: | The individual karst types are quite complex and the epikarst are closely related with the geologic conditions and the karst developing history and process in southwest Hubei karst area. The epikarst developing intensity and its varying regulation under different tectonic parts, rock layers, lithology and geomorphologic locations as well as cycling （recharge, runof and discharge） features of the deep karst water are studied through field investigation and collection of geologic exploration data along the ＂Hu-Rong-Xi＂ highway with systematic engineering geology analytic method mainly. The spatial developing intensity of epikarst is discussed in detail and it is quantitatively put forth for the 1^st time that the maximum depth epikarst developed in this area is 56. 54m and minimum depth 4. 5m in the paper. And furthermore, the general regulation of epikarst development gets stronger from mountain top and ridge to foot and valley is expounded. |
