摘　　要：通过模拟水管式沉降仪埋设安装条件,按照监测规范及相关技术要求,结合水管式沉降仪测值计算及修正原理,对糯扎渡水电站水管式沉降仪模拟实验场地布置、材料要求、安装及坝料回填过程进行实验。监测数据结果表明,实验测点最大沉降分别为145 mm和37 mm,水管式沉降仪器整体测值稳定,波动变化较小,对于在糯扎渡高土石坝具有良好的适用性。The site layout, required materials, installation and dam material backfill are experimentally researched to simulate the installation conditions of pipe-tube settlement gauge in Nuozhadu high core rockfill dam. The experiment is in accordance with the requirements of monitoring standards and related technologies and considers the calculation and correction principles of gauge＇s measured value. The experimental data show that the maximum settlements of two measuring points are 145 mm and 37 mm respectively, and the measured values are stable. The gauge has a good applicability for Nuozhadu Dam.
