混凝土应力应变观测的探讨

Discussion on Stress and Strain Observation for Concrete Dams

应力应变观测是混凝土坝内部观测的主要项目,根据应变计、无应力计观测资料,用变形法计算混凝土实际应力时,需要重视观测资料的误差处理,并对无应力计的布置、实际应力存在的误差、应变计组的布置进行了一些探讨,可供设计院、水库大坝运行管理部门参考。

Stress and strain observation is one of the main items in internal observation of concrete dams. Error processing of observed data is worth great attention during actual concrete stress calculation by use of distortion method referring to observed data by strain sensors and no sensor observation. Besides, this article discussed collocation of no sensor observation and strain gauges as well as possible errors of actual stress, which can be reference to designing institutes, and operation administrations of reservoirs and dams.
