【摘要】 目前,黄河下游河道整治工程布点工作已基本完成,近年来,根据已建工程情况,黄河水利委员会规划安排的河道整治工程多为已建工程的上延、下延等续建工程。而实际上,为控制小水畸形河势不少续建工程布置的位置已超越原中水整治方案的布置范围。为减小这部分坝垛对中小洪水以及滩槽水沙交换产生的不利影响,研究分析同时满足自身稳定、不影响滩槽水沙交换和排洪,又能控导河势,且拆除简单、经济合理的坝垛结构型式——组装式导流桩坝十分必要。因此,作者在导师的指导下开展了黄河下游组装式导流桩坝设计及应用的分析研究,主要工作和成果如下:(1)从不同坝型结构形式的性能对比分析确定了组装式导流桩坝结构形式。(2)结合桩坝的实际运用工况,确定了组装式导流桩坝的平面布置方案、设计流量与坝顶高程,利用冲刷深度常用计算公式对冲刷深度进行了计算和确定、对坝体管桩运用进行了受力分析与计算、根据计算结果和相关规范确定了桩坝的结构设计,并对管桩进行了配筋计算。(3)根据不同冲刷深度验算结果和试验工程运用观测成果比对分析,推荐了组装式导流桩坝桩坝管桩合理桩长和冲刷深度计算公式。更多还原

【Abstract】 At present,the work of the river course of the lower reaches of the Yellow River has been basically completed.In recent years,according to the situation of the existing projects,the river regulation works planned by the Yellow River Conservancy Commission are mostly extended and delayed Continued construction.In fact,many of the continued construction of the layout of the location has gone beyond the original water treatment program layout range.In order to reduce the adverse effect of this part of the dam on the flood and the water and sediment exchange of the beach.Therefore,the study at the same time to meet their own stability,does not affect the beach water and sediment exchange and drainage,but also control the river,and the removal of simple,easy to move,economically reasonable structure of the structure of the dam-Assembled diversion pile the dam.Therefore,under the guidance of the tutor,the author carried out an analysis and research on the design and application of the downstream construction-type diversion pile dam of the Yellow River.The main work and results are as follows:(1)The structural form of grouted diversion pile dam is determined from the performance comparison and analysis of different types of dam structures.(2)Combined with the practical application of dike condition,to determine the pile packaged diversion dam crest elevation plane layout scheme,design flow and,using the formula of scour depth are commonly used to scour depth are calculated and determined,and the dam body pipe pile using the force analysis and calculation,according to the calculation results and the relevant specification to determine the structure of the dike design,and the reinforcement for the pipe pile is calculated.(3)According to the verification results of different scour depth and the comparative analysis of the observation results of the test project,the calculation formulas for the reasonable pile length and scour depth of pile-dam pile-dam pipe piles of packaged diversion piles are recommended.更多还原
