摘要
通过对江坪河水电站河间河湾地块两个可能渗漏地段地层结构、水动力场、岩溶发育等的综合分析,提出两个地段上的控制孔ZK1、ZK3的水位在垂直和水平方向上水动力中所代表的的局限性和作为防渗设计依据的不充分性;并通过进一步的勘探,充分肯定了ZK1区域不存在岩溶渗漏问题,而在ZK3区域存在岩溶渗漏通道。其研究和分析方法对具有复杂水动力场的同类型岩溶峰丛山区进行工程建设具有一定意义。
Base on the analysis of the stratum structures, the hydraulic field and karst development for two main possible karst seepage sub-area in the bay area of Jiangpinhe hydropower station, this paper puts forward the representative of the water levels of the two drillings ZK1, ZK3 are limited in horizontal and vertical directions, and it is not effective and not correct as foundations of anti-seepage design. Through the further survey, it is confirmed that the sub-area near ZK1 has no seepage and the sub-area near ZK3 is possible. The analysis method is more significance for the same karst peek-cluster depression that has complex hydraulic field.
