樊口船闸人字门背拉杆预应力优化计算与调试

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

按三维有限元计算了樊口船闸人字门自由悬挂时 ,在单项荷载 (自重、风、水、单根背拉杆施加单位预应力 )作用下人字门的应力与位移 ,对樊口船闸人字门背拉杆预应力进行了优化设计 。

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.
