摘要
大坝外部变形安全监测的诸多项目，大多是近十数年来才开始在水电工程上逐渐被采用的，虽然作为水平位移监测项目之一的倒垂线法由来已久，但其施工的难度是水电行为共认的。本文即是从这方面入手，结合黄河大峡水电站工程的施工实践，总结了一些施工经验，以供交流参考。
Most items of dam external deformation monitoring are progressively adopted in hydropower projects during the last ten years. Although the monitoring of horizontal displacement is measured by reversed pendulum method for a long time, its difficulty is evident. Therefore, initiating from the method, in conjunction with implementation of Daxia Hydropower Station on the Yellow River, the experience is summarized, which may provide some reference for other projects.
