|
摘要
通过实例比较了2种常用的抛物线形渠道水力最佳断面参数,得出二次抛物线渠道的水力性能优于半立方抛物线形渠道,并推导出了二次抛物线渠道实用经济断面的计算公式,提出了详细的计算步骤,给出了二次抛物线渠道实用经济断面水力计算表以供设计人员使用。同时,根据渠道工程实际应用情况和现行规范要求,提出了抛物线形混凝土衬砌渠道标准化结构形式,计算得出了常用抛物线形混凝土渠道结构尺寸、不同比降流量表,在实际工程应用中可根据设计渠道的具体情况进行选用。
Comparison between two kinds of commonly used parabolic canal hydraulic best section parameter through an example was made.It reached that the water conservancy performance of the two parabolic canal was better than the semi cubic parabolic canal,and the calculation formula was deduced.The detailed calculation steps were proposed,and the hydraulic calculation table for the practical economic section of the two parabolic canal was given.At the same time,according to the actual application of the canal project and the current specification requirements,the standard structure of the parabolic concrete lining canal was put forward,and the structure size of the common parabolic concrete canal and different ratio of the flow meterwere calculated.According to the specification situation of design canal,different values in practical engineering application could be chosen by the engineers.
