Abstract: By use of propagation of surface wave in concrete, the RL-2000 series of non-destructive detector was adopted for crack depth testing for Wuqiangxi lock. What’s more, part of the cracks were again tested by drilling and ultrasound method, the results were basically the same with the former ones.

摘要： 根据表面波在混凝土中的传播特性，采用RL－2000系列无损检测仪对五强溪水电站船闸裂缝深度进行检测，并选取部分裂缝采用超声法和钻孔法验证裂缝深度，结果基本一致。
