摘　　要：传统仪器已难以适应300 m级超高土石坝对安全监测的技术要求,如心墙内水平位移和垂直位移监测、上游堆石区蓄水及运行期的垂直位移监测,目前国内外尚无有效的改进监测手段和方法。提出了采用柔性测斜仪对心墙分层水平位移、心墙分层垂直位移以及上游堆石区分层垂直位移进行监测的新方法,详细介绍了仪器工作原理及监测布置方案,对类似工程有参考价值。For safety monitoring of 300-meter super high earth-rock dams,the traditional instruments have difficulties to meet the technical requirements in aspects such as monitoring of horizontal displace⁃ment and vertical displacement in the core wall,as well as vertical displacement monitoring of upstream rockfill zone during water impoundment and operation.Currently,there are no effective monitoring meth⁃ods domestic and abroad.This paper puts forward a new method for monitoring of both horizontal and vertical displacement of the core wall,and the vertical displacement of upstream rockfill zone by using the flexible inclinometer.The working principle of the instrument and its monitoring scheme are intro⁃duced in detail,worth reference.
