杨柳溪水库灌区渠系建筑物优化设计

摘要

针对杨柳溪水库灌区地形地貌、地质条件较复杂,沿线部分渠段边坡稳定性较差、易形成高陡边坡等问题,经现场踏勘结合河渠交叉建筑物方案比选原则,优选渠系整体布置方案和渠系建筑物结构形式.经水力计算、应力计算等论证分析,结果表明渠系建筑物结构、型式、过流能力和防洪特性等,均满足SL482—2011规范要求,优化设计方案具有较高的技术可行性和经济合理性.%Due to the complex conditions of topography and geology, the poor slope stability is easy to form a high and steep slope along the canal section in Yangliuxi Reservoir irrigation area. Based on the site reconnaissance and the comparison of canal buildings in the intersection of river and canal, an overall layout plan and canal building structure has been optimally chosen. Analyzed by hydraulic calculation and the stress calculation, it is proved that the structure, type, flow capacity and flood control of the canal buildings meet the requirements of SL482—2011, and the optimization design scheme has high technical feasibility and economic rationality.
