【摘要】 我国一些地区资源丰富,但就近水源缺乏,不得不采用长距离有压重力输水。长距离输水工程管线长、起伏大,管道工程投资高,因此对其进行优化设计意义重大。结合工程实例采用线性规划法对长距离输水管线进行了优化设计,并用特征线法计算了管道水锤压力。更多还原

【Abstract】 Some areas in China are abundant in resources,but short of water source nearby,so the pressured gravity water transportation in long distance must be adopted.Because of the long pipeline,the drastic undulating ground and the high investment of the water transportation in long distance,it is important to optimize the pipe work.By using the linear programming method,the optimum design for the pipeline of the water transportation in long distance is made according to an actual engineering,and the water hammer pressure of the pipeline is calculated by using the characteristic method.更多还原
