闸底板优化设计

Optimal Design of Sluicing Floor

为了提高涵闸底板的设计质量和设计水平，从实际涵闸工程设计入手，提出了变截面双悬臂闸底板的计算模型；同时采用满应力准则法设计了六种型式的双悬臂闸底板。结果表明，采用连续板式或分离式闸底板式设计可节省工程量２０％以上。

o improve the design quality and level of sluicing culvert,the analytic model of double out-stretch sluicing floor with variable cross section is provided on the basis of practicdl engineering design experience. The calculaton chart;for six different forms of double out-stretch sluicing floor are also given in the paper. The criterion of full stress optimization is applied in the calculation.The results indicates that about 20%of engineering cost could be saved compared with model of continuous of discrete sluicing floor.
