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.
