文章全面介绍了黄河小浪底工程大坝变形，渗流，应力应变和震动反应等观测项目以及观测仪器的布设情况。设计遵循了突出重点，兼顾全局，力求达到少而精的原则，把变形和渗流作为观测重点，同时兼顾应力应变和震动反应的观测，以达到监测工程安全，校对设计的目的。 The paper introduces the observation items such as deformation, seepage, stress and strain and vibration response of the Xiaolangdi Dam and the layout of observation instruments. The design follows the principle of emphasizing the key points, considering the overall situation and striving for the principle of being small but precise, taking the deformation and seepage as the key points for observation, taking into account the observation of stress, strain and vibration response so as to achieve the purpose of monitoring the safety of the project and proofreading the design.
