【摘要】 介绍了电磁式沉降管在公伯峡面板堆石坝变形观测中的应用情况,对电磁式沉降管观测成果进行分析,并与水管式沉降管及三维有限元计算成果进行比较,可看出电磁式沉降管观测成果规律性好、合理、可靠,可用来观测面板堆石坝沉降变形。电磁式沉降管在公伯峡面板堆石坝变形观测中的成功应用可为其它类似工程提供可借鉴的经验。更多还原

【Abstract】 The application of electromagnetic settling tube is presented in the deformation observation of Gongboxia concrete face rock-fill dam,and its observation results are analized in comparison with those of hydrostatic settling tube and three-dimensional finite element calculation.It can be seen that the electromagnetic settling tube is reliable and rational with good regularity so as to observe the settlement and deformation of the rock-fill dam. The electromagnetic settling tube has been successively applied in Gongboxia concrete face rock-fill dam,and the experience can be provided for reference of similar hydropower projects.更多还原
