Optimization and adjustment of prestress of diagonal brace of mitre gate in Fankou Shiplock

By using the three dimensional finite element method, the stresses and displacements of the free hanging mitre gate applied by a single load(weight, water, wind, unit prestress applied on a single diagonal brace), are calculated. The prestress of the diagonal brace of the mitre gate is optimized. The adjustment process of prestress of diagonal brace is introduced.
