天生桥二级水电站引水系统安检中的物探检测

Checking Conduit System of TianshengqiaoⅡHydropower Station Using Physical Survey in Safety Inspection

引水发电系统在水电工程运行中占据极其重要的位置,其隐埋性和涉及到的地质问题的复杂性决定了安检工作的难度,尤其对于规模大的深埋隧洞,要在极短的时间内完全了解隧洞及其围岩在运行过程中所发生的变化,以排除隐患、确保下一步安全运行,物探方法显示了其快速、可靠、无损的特点。文章介绍的是天生桥二级水电站I号引水系统安全运行检查工作中物探方法的使用效果。

Conduit system plays an important role in operation of hydropower engineering. Due to its concealment and complication of geological problems involved with it, there are many difficulties in safety inspection work, specially, to largescale deeper tunnels. Physical survey method has some advantages such as quick, liable, harmless and etc., it can totally understand all changes of the tunnel and its rounding rock in operation in very short time for eliminating hidden dangers and ensuring safety operation in the next time. The paper introduces the results using physical survey method in safety inspection to conduit system of Tianshengqiao Ⅱ Hydropower Station. 
