大石门水电站大坝安全监测设计与资料分析

Dam safety monitoring design and data analysis of Dashimen hydropower station

摘要:

大坝安全监测关系到大坝的施工质量和运行安全，是工程施工和运行期的重要工作。针对沥青砼心墙堆石坝的特点，通过优化监测设计方案，设置关键监测项目，选择对沥青砼心墙结构影响小的监测仪器和安装方式，实现大坝关键部位的安全监测。对近 10 a 的监测数据进行处理和分析，结果表明监测仪器工作正常，监测数据连续可靠，大石门水电站大坝和沥青砼心墙运行稳定，说明大坝安全监测设计方案合理、正确，为全面掌握和了解大坝的施工质量、运行状况等发挥重要作用。

Abstract:

Dam safety monitoring is related to dam construction quality and operation safety. It is an important work of engineering construction and operation period. According to the characteristics of the asphalt concrete corewall rockfifill dam, the article optimizes the monitoring design scheme, sets up the key monitoring programs, selects monitoring instruments and installation methods that have little inflfluence on the asphalt concrete core-wall structure to realize the safety monitoring of the key parts of the dam. By processing and analyzing monitoring data of nearly 10 a, the results show that monitoring instrument works normally, monitoring data are continuous and reliable, the running stability of Dashimen hydropower station dam and asphalt concrete core-wall is well. It illustrates that the dam safety monitoring design scheme is reasonable and correct, and plays an important role for fully grasping and understanding the construction quality and operation status of dam.
