摘　　要：针对沥青混凝土芯墙堆石坝坝体和坝基多重介质物理力学性状差异大、应力应变状态复杂、坝体渗漏探测和处理难度大的问题,基于工程实例,形成先分析地质、设计和施工过程资料,再利用物探为辅、钻孔探测为主的综合探测手段,进一步确定大坝渗漏范围和性质;同时针对堆石坝堆石结构特点制定了套阀管法和多种浆液体系的控制性灌浆工艺。采用上述方法进行处理后,大坝总渗漏量从最初的700多L/s减少到了6.4 L/s,处理效果明显。For the physical mechanic characters of multiple mediums of dam body and foundation of asphalt concrete core wall rockfill dam are quite different, stress-strain conditions are complicated, dam leakage detection and treatment are difficult, comprehensive detective measures are formed on the basis of practical cases： firstly, analyzes the geology, design and construction information; secondly taking borehole detecting as the main means and geophysical prospecting as auxiliary to further confirm the dam leakage range and property; meanwhile sleeve valve tube method and various slurry system controlled grouting technology is formulated. After treated by above mentioned measures, the total leakage of the dam is reduced from more than 700 L/s to 6.4 L/s, the treatment effect is obvious.
