中文摘要:
      治导线规划是河道整治中的重要环节,然而现行整治规范只限制了治导线设计参数的取值范围,设计中经验性较强,未考虑设计参数之间的制衡关系。基于前人对弯道输沙及送溜能力的研究,兼顾弯道输沙及送溜能力,基于制衡机制得到最优治导线的设计目标函数,通过目标函数求最小值解得治导线的设计参数。将此方法应用于河势控制良好的河段,计算得出的制衡方程最小值、治导线设计参数、设计参数与河段实际情况基本一致,说明方法的可行性,并使用此方法对黄河内蒙古皮房圪旦-白音赤老河段进行治导线规划。
英文摘要:
      Design of regulation line is an important content in river regulation. Only the ranges of design parameters are given in the latest code for design of river regulation,which have to be determined by expe-riences in the design. Based on the study of the water and sediment transport capacity and the flow guid-ing capacity of the river bend, the check and balance mechanism is suggested in design of regulation line. As an example, the regulation lines of Daliusi-Laojunmiao reach of the Yellow River are designed by this method. The design method is feasible by comparing with the actual river morphology. At last, the regula-tion lines between Pifanggedan and Baiyinchilao reach of the Yellow River are designed by this method.
