摘要： 水平垂直位移计——引张线式位移计和水管式沉降仪，一般布置在监测条带内，作为土石坝内部变形监测的主要手段，在国内得到广泛应用。但传统的一般土石坝水平垂直位移计安装方法已渐渐不适用于高土石坝。笔者系统归纳总结了国内已建和在建高土石坝水平垂直位移计主要安装方法，对比分析了其各自的优缺点，推荐采用监测条带开挖坡降1.3%、不开挖管路沟槽的设计方案。

Abstract: Horizontal and vertical displacement meters, i.e. horizontal displacement guage of tensional wire and hydraulic overflow settlement gauge, are generally arranged in the monitoring strip, which are main means of deformation monitoring of embankment dam and widely used in China. However, the traditional installation method of horizontal and vertical displacement meter for embankment dam is gradually not suitable for high embankment dam. This paper systematically summarizes the main installation methods of horizontal and vertical displacement meter for high embankment dams in China, and compares their advantages and disadvantages. It is recommended to adopt the design scheme of excavation slope of 1.3% for monitoring strip, without pipe groove.
Key words: high embankment dam, monitoring strip, deformation monitoring, horizontal displacement guage of tensional wire, hydraulic overflow settlement gauge
