Abstract

After running for half a year, periodic inspection to a discharge sluice shows that cracks in the direction of water current appear in the bottom board of most of sluice lockage chamber. Stress computation under the design conditions and the working conditions after cracks appeared are carried out with 3D-FEM respectively. The results indicated that the stress of the bottom board is still within the allowed range, the structure is safe from the view of the stress. But considering the defective parts of bottom surface and interlayer surface are likely to be connected with vertical cracks, seepage follow channel will be formed, and it will affect the long-term safe operation of the whole structure, it is suggested that cracks in bottom board should be repaired.
