摘要
黄河甘泽坡水利枢纽位于黄河北干流南端,工程区为石灰岩区,广泛发育有岩溶,岩溶的发育对大坝造成不良影响,因此认识岩溶的发育特征显得十分重要。通过长期的野外地质勘察及大量的野外资料分析,论述了工程区岩溶的发育特征,并总结了工程区岩溶多顺构造发育,岩体透水性具有方向性,东西强、南北弱,呈"东西成带,南北脉联"的特点,为大坝的规划与设计提供了可靠的地质依据。
The Ganzepo hydro-junction is located in the southern tip of north main stream of Yellow River,in the limestone region,with the feature of karst developed widely,which has harmful effects to the layout of the dam,so the study on the characteristics of karst development is very important.Based on long-term geological investigation in field and data analysis,the characteristics have been found out.It comes to the conclusions that the karst mainly develops along geological structure and the permeability of the rock has a certain direction,with the feature of more strongly in west-east direction than north-south,which provided a reasonable basis for the planning and designing of the dam.
