摘要
在中小型河流喀斯特伏流河段附近或者直接封堵伏流洞,利用伏流山体做坝建库的工程勘察,是以往水利水电工程勘察工作中少有遇到的。客观上伏流河段的喀斯特和水文地质条件普遍复杂,修建水库所涉及的主要工程地质问题、复杂程度、能否成库与处理代价是人们所关心的。文章结合贵州喀斯特地区数个涉及伏流河段的开发利用工程,探讨了伏流河段水利水电开发可能遇到的主要工程地质问题与工程评价。
In medium-and small-sized rivers, project investigation for constructing dams at karst underground reaches or blocking underground caves by using their upper rock masses, is seldom made. Hydrogeological conditions of karst underground reaches are generally complex. In the process of constructing a dam, people care about such problems as engineering geology, complexity, the possibility of reservoir, and project cost. In recent years, our institution has undertaken several projects in underground reaches. This paper introduces some engineering geological problems, gives estimation and draws a conclusion.
