摘要
杨房沟水电站大坝为高155 m的混凝土双曲拱坝,坝身布置有表孔、中孔、生态泄放洞等,坝体结构受力较复杂。根据坝址地质条件、结构形式、运行工况、荷载条件等资料,遵循有关规范和工程经验,对该拱坝进行了安全监测系统的设计。介绍了拱坝安全监测系统设计的原则,安全监测系统的组成,包括监测部位、监测项目及监测仪器的选取等,总结了监测系统的特点。设计过程中充分考虑了施工期、蓄水期及运行期各阶段的工程安全监测需要,提出了系统合理的拱坝安全监测自动化系统设计方案,该系统在工程的施工期、蓄水期阶段得到了良好应用。
The dam of Yangfanggou Hydropower Station is a 155 m high concrete double-curvature arch dam.The dam body is arranged with surface orifices,middle orifices and ecological drainage tunnels,so the stress status of dam body is complicated.The dam safety monitoring is designed based on the geological conditions,structural forms,operating conditions and load conditions and in accordance with relevant specifications and engineering experiences.The design principles of arch dam safety monitoring system and the composition of safety monitoring system including the selection of monitoring sites,monitoring items and monitoring instruments are introduced,and the characteristics of monitoring system is summarized.The needs of engineering safety monitoring during construction period,water storage period and operation period are fully considered in the design of monitoring system,and a systematic and reasonable automatic design scheme of safety monitoring system is put forward.The automatic safety monitoring system has been well applied in the construction period and water storage period of the project.
