摘要
针对响水水库坝址区岩溶发育强烈,可能存在经岩溶管道、裂隙产生近坝库岸渗漏或绕坝渗漏等问题,经现场地质调查和平硐钻孔勘察,从坝基持力层、坝基压缩变形、坝基(肩)抗滑稳定和防渗等方面对大坝工程地质条件进行详细论证分析.结果表明,坝址区工程地质条件良好,坝址区无规模较大的不良地质条件,岩溶渗漏通道经帷幕灌浆防渗处理后,蓄水成库条件良好,适宜重力坝建设.
Abstract
Karst in the dam site area of Xiangshui reservoir is strongly developed,and there may be leakage near the dam bank or around the dam through karst pipelines and fissures.Through the field geological survey and adit drilling survey,this paper demonstrates and analyzes the dam engineering geological conditions in detail from the aspects of dam foundation bearing layer,dam foundation compression deformation,dam foundation(shoulder)anti sliding stability and anti-seepage.The results show that the engineering geological conditions in the dam site area are good,and there are no large-scale adverse geological conditions in the dam site area.After the curtain grouting anti-seepage treatment,the karst leakage channel has good conditions for water storage and reservoir formation,which is suitable for the construction of gravity dam.
