摘要
埋设在大坝内部的仪器性能关系到能否反映大坝的运行状况,提供准确的监测数据,发挥应有的监测作用。通过满拉水利枢纽工程实例,介绍埋设在大坝内部的钢弦式仪器的工作原理,探讨产生故障可能的因素,按照现行技术规程,对埋设仪器进行各项性能检验,通过检验数据和历史数据进行分析,判断埋设在大坝内部的大部分钢弦式仪器的工作特性满足其基本性能和规范要求,为工程监测系统的改造设计、施工、运行评价提供依据,对同类工程有一定参考价值。
Abstact：The performance of sensors embedded in dams is vital to the operation of dams, accuracy of monitoring data, and fulfillment of functions. Through the case study of Manla hydro-project, this article elaborates the operation principles of vibrating wire sensors embedded in dams, and discusses the possible reasons for malfunctions. According to the current technical specifications performance tests of the embedded sensors are carried out. The characteristics of most embedded sensors can meet requirements by the analysis on tested data and historical data, based on which, further renovation design, construction and operation assessment can be implemented. This article also provides reference to similar projects.
