| 摘 要： | 大坝水库坝后坡长期渗漏严重,为此采用CCTV管道内窥仪、探地雷达、高密度电法仪和表面波地震仪等先进仪器设备对坝体渗漏原因进行检查探测,根据探测成果提出采用旋喷桩墙的防渗治理方案,通过科学施工后,坝体防渗墙平均渗透系数小于1.0×10~(-5)cm/s,坝体渗漏得到有效控制,大坝渗漏探测治理模式可供类似工程参考。

| Abstract: | There is serious long-term leakage in downstream slope of Daba reservoir dam, CCTV pipe endoscope, ground penetrating radar, high density electrical instrument and surface wave seismograph and other advanced equipments have been used to detect the reasons of dam leakage.According to the results of detection, anti seepage scheme of the technology of spiral spray pile has been proposed.Through scientific construction, seepage coefficient of dam wall is less than 1.0×10-5cm/s, and the seepage of dam is treated effectively.The dam leakage detection and control mode in this paper can be used as a reference for similar projects. |
