摘　　要：针对目前差阻式应变计评价在综合性方面存在的不足,以良浅水电站大坝埋设的差阻式应变计工作状态评价为例,从现场调查、现场测试和长期观测精度等3个方面出发,采用定性和定量分析相结合的方法,对差阻式应变计工作状态评价的内容、方法、标准和等级等问题进行了较为系统的研究,对差阻式仪器工作状态评价提供了参考依据和工程经验。At present, the evaluation of working status of the differential resistance strain gauge is still insufficient in terms of comprehensiveness. So, here, taking the working status of the differential resistance strain gauge in Liangqian Hydropower Station as an example, the content, methods, standards and grades of comprehensive evaluation for the differential resistance strain gauge are systematically studied from the aspects of field survey, site testing and long-time observation accuracy by use of qualitative and quantitative analyses. The research results can provide reference and experience for evaluating the working status of the differential resistance strain gauge.
