Abstract: To facilitate the application of measured stress to evaluate dam concrete stress in practice, by analyzing the differences between the measured stress and the designed stress and their causes, and combining with calculation cases, a set of evaluation method and index is proposed, which is of reference significance for the application of the measured stress of dam concrete and the stress evaluation of hydropower dams during operation.

Key words: dam, concrete stress, measured stress, designed stress, evaluation standard

摘要: 为便于在工程实际中应用实测应力进行大坝混凝土应力评价,通过剖析实测应力与设计应力存在的差异及其产生原因,结合工程计算实例,研究并提出了一套适用于大坝混凝土实测应力的评价方法和指标,对应用大坝混凝土实测应力结果及开展运行期水电站大坝应力评价具有一定的参考意义。
