摘要
坝塘水库是利用天然构造溶蚀洼地作库盆的注入式水库。地质条件复杂,水库地处高地震烈度区(地震基本烈度为9度),同时库盆悬托,库周是低邻谷,存在灰岩喀斯特渗漏、喀斯特塌陷、不均匀沉陷等问题。本文论述建库存在的工程地质问题和相应的工程措施进一论述。
The basin of Batang reservoir is a natural erosin depression with complicated geological (conditions), which is distributed in a high intensity earthquake area(basic (earthquake) intensity 9). And the reservoir basin is hanging up, with low valleys near it. Therefor, there are problems of karst seepage, collapse and uneven sinking, etc. The engineering geological problems and corresponding engineering (measures) in reservoir construction are discussed in this (paper.)
