Abstract: By analysis on monitored data of stress and strain of the reinforced concrete slab of Shanxi dam, its distribution and change trend were obtained. Aiming at the problem of large strain of concrete slab and stress of the steel bars on elevation of 70 m, combined with inspection of the cracks here, the stress of slab was analyzed and the operation safety of slab was assessed.

Key words: Shanxi dam, face slab, stress and strain, analysis

摘要： 通过分析珊溪大坝混凝土面板应力应变监测资料，掌握了面板混凝土应变和钢筋应力的分布情况和变化规律。针对70 m高程处面板混凝土应变和钢筋应力偏大现象，结合所处部位具体情况和面板裂缝检查情况，重点对该部位面板的应力状态进行分析，并对面板的运行状况进行安全评价。
