汾河二库碾压混凝土重力坝的原型监测的设计原则为：结合坝的等级、坝高、地质、结构形式等条件提出观测及布置要求．观测项目和测点布设要考虑碾压混凝土筑坝的特点，全面反映大坝的工作状况，并做到少而精．观测坝段应选择地质条件复杂或具有代表性坝段．观测设备的选用，应做到观测方便、直观、快捷、精度符合要求，各项观测值能相互校核，并保证观测作业有良好的交通及照明条件．通过已经取得的部分观测资料的整理分析，说明了仪器布正是合理的，仪器埋设技术是成功的．
The design principle of the prototype monitoring of Fenhe II reservoir gravity dam is that the requirements of observation and layout are put forward based on the conditions of grade, dam height, geology and structure of the dam. The observation project and the layout of measuring points should consider the characteristics of roller compacted concrete dam and fully reflect the working conditions of the dam and make it small and fine. Observation dam section should choose complex geological conditions or representative dam section. Observation equipment selection, should be easy to observe, intuitive, fast, accurate to meet the requirements, the observations can be checked with each other, and ensure that observation work has good traffic and lighting conditions. Through the analysis of the partial observation data that has been obtained, it is proved that the instrument cloth is reasonable and the instrument embedding technique is successful.
