T形墩消力池消能率的计算及优化设计试验
Study on calculation of energy dissipation ratio and optimal design test of stilling basin with T-shape baffle
摘要
Abstract
Based on a model test of a hydraulic project in the Xinjiang Kensiwate district, a new type of energy dissipater with a deck for preventing the torrent from moving upward was presented, that is a stilling basin with a T-type baffle. A formula for calculating energy dissipation ratio of this new energy dissipator was derived from the energy equation. Comparision between the calculation result employing this formula and the measured result shows that the errors can be neglected for practical projects. Hence, the formula can be used to calculate energy dissipation ratio of a stilling basin with T-type baffle in practical projects. To analyze the influence of the stilling basin' s length and the shape of the T-type baffle on energy dissipation effect, hydraulic tests for the stilling basin with six kinds of T-type baffle were carried out. In addition, the energy dissipation ratio for every test condition was calculated using the formula proposed in this paper. It can be concluded that the optimal length of the stilling basin is 52. 2 m, the optimal shape of the baffle' s leg is a trapezoid, and the optimal shape of the baffle block is an arc.关键词
