摘要
针对部分沥青混凝土心墙坝出现渗漏情况,为判定沥青混凝土心墙坝渗漏的部位及通道,需采用多种检测方法对坝体渗漏情况进行综合分析和判定。列举了多个工程应用实例,对沥青混凝土心墙坝渗漏检测方法如水下声纳检测、孔内彩电观测、示踪连通试验、坝体内水位分析和物探检测,以及混凝土防渗墙和控制灌浆修复坝体防渗体系方案及其影响因素进行了综述,以期为类似工程提供借鉴。
Aiming at the seepages occur from a part of earth-rockfill dams with asphalt concrete core,it is necessary to adopt various detecting methods to comprehensively analyze and judge the seepage inside of the dam body in order to judge the location and passage of the seepage. Several engineering application cases are listed herein for reviewing the seepage detecting method for the earth-rockfill dam with asphalt concrete core,i. e. under water sonar detection,color TV ddllhole observation,connection tracing experiment,analysis on water level inside of dam body,etc. the concrete cutoff wall and the scheme of the controlled grouting for repairing the anti-seepage system of the dam as well as their effect factors,so as to provide some references for the similar projects concerned.
