摘要
以太平河河道整治工程为例,为推求天然河道沿程设计洪水位,以稳定非均匀流为计算依据,按伯努利能量方程对河道水位进行推求,并对该河岸的护岸设计方法进行了分析研究。研究结果表明,采用伯努利能量方程依次往上推算水面线,符合水面线推算原则,计算得出的水面线结果均在合理范围内。通过分析护岸设计方案,松木桩的抗剪、抗弯能力差,易折断,且松木桩方案投资相比C60仿木桩方案高,因此C60仿木桩更适合本工程的河道护岸。
Taking the Taiping River regulation project as an example,in order to calculate the design flood level along the natural river course,the water level of the river course is calculated according to Bernoulli energy equation based on the calculation of stable non-uniform flow,and the bank protection design method of the river bank is analyzed and studied.The results show that the calculation of water surface line by Bernoulli energy equation is in accordance with the principle of water surface line calculation,and the calculated results of water surface line are within a reasonable range.Through the analysis of the bank protection design scheme,the pine pile is poor in shear and bending ability,easy to break,and the investment of pine pile scheme is higher than that of C60 imitation pile scheme,so C60 imitation pile is more suitable for the river bank protection of this project.
