摘　　要：我国土石坝数量众多,经长时间运行易出现裂缝、渗漏等病害隐患,严重威胁大坝安全。以某水库土石坝为例,结合其散浸特征,采用高密度电法、地震折射波法、瑞雷波法等物探方法进行综合探测,查明散浸渗漏通道分布范围,取得了良好效果。There are a large number of earth-rock fill dams in China,various potential dangers such as the crack and leakage are prone to occur after long-term operation,which seriously threaten the dam safety.Taking the earth-rock dam of a reservoir as an example,combined with its soaking out character-istics,comprehensive detection was carried out using the multi-electrode resistivity method,seismic re-fraction method and Rayleigh wave method to identify the distribution range of soaking out channels,achieving good results.
