摘要
引水发电隧洞在水电工程中占据极其重要的位置，其隐埋性和所涉及工程地质问题的复杂性决定了隧洞安检工作的难度，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、确保下一步运行安全，物探方法显示了其快速、可靠、无损的特点。文章介绍的是某水电站Ⅱ号引水发电隧洞安全检查工作中物探方法的使用效果。
Power conduit system is very important in hydropower project. It is difficult for tunnel safety checking, as a result of power conduit is under the ground and covers complicated geological problems. In order to understand the variation of tunnel and surrounding rock in the movement process within the very short period, and remove the hidden danger, and ensure the operation safety, geophysical method shows its properties of acceleration, reliability and harmless. The paper describes the effect of geophysical method used in the safety checking of No. 2 power conduit system of a hydropower station.
