摘要
从多年大坝监测的历史经验看,坝体监测是一项长期的监测任务,在爆发特大洪灾、地震等突发事件时需要及时掌握坝体在平面位移和沉降几何变形量的变化情况,为上层决策提供重要的参考依据。为了保障大坝安全、稳定、长期运行,建立了一套自动化监测系统。但大坝附近环境较为复杂,往往存在较大的多路径效应,影响自动化监测系统的监测精度和结果。为了验证该系统在大坝环境下对大坝变形监测的有效性,在新安江水电站进行了多路径效应的环境应用测试。测试结果表明,本系统可以在大坝环境中有效应用,但受多路经效应影响较大,为进一步提高监测精度还需要增加抑径装置抑制多路经效应。
From the historical experience of many years of dam monitoring,dam monitoring is a long-term monitoring task, the outbreak of serious floods,earthquakes and other emergencies need to grasp the dam in plane displacement and deformation settlement of geometry changes,for the upper decision-making to provide very important reference.In order to ensure the safety,stability and long-term operation of the dam,a set of automatic monitoring system has been set up.In the vicinity of the dam,the environment is more complex and often has a large multipath effect,which affects the monitoring accuracy and results of the automatic monitoring system.In order to verify the dam deformation monitor effectively of the system under the dam environment,the environmental test of the multipath effect at Xin'An River hydropower station is carried out.The test results show that,the system can be effectively used in the dam environment.In order to further improve the monitoring precision,the multi channel effect should be increased by increasing the anti diameter device.
