黄河下游预应力管桩丁坝结构优化设计研究
The Optimization Design Study Based the Lower Yellow River Prestressed Pipe Pile Spur Dikes Structure
摘要
Abstract
New prestressed pipe pile is presented on the basis of analysis of the characteristics of traditional rockfill groins. Take Huayuankou for example, the combination of the orthogonal experiment principle of the spur dikes structure design, the overall displacement law with the parameters change of spur dikes is analyzed by FLAC3D finite difference code. The numerical results show that spur dikes of the horizontal displacement of the contribution of primary and secondary order as follows: the scour depth of pile length > flow rate > pile spacing and pile diameter > contacts beam size; under the operation conditions of flood flow 4 000 m , water velocity of 3 m/s, the scour depth is 16m operating conditions, the spur dikes structure program of the pile length 25m 0. 6m pile spacing, pile diameter is 600 mm, contact beam size is 0. 6 m×0. 6 m is optimal, to the safety factor of strength reduction method is 1.32.关键词
