中文摘要:
      航道整治中整治线宽度的确定是整治成败的关键因素之一。在考虑山区河流挖槽稳定性以及船舶上滩能力基础上对整治线宽度计算公式进行改进,提出适合山区河流沙卵石浅滩整治线宽度的计算公式。并通过工程实例借助数学模型对计算的整治线宽度进行验证并提出优化。整治线宽度的确定是一个系统性工作,传统的整治线宽度计算公式与该公式的计算值仅可作为参考值。为达到良好的整治效果,需要通过数学模型以及河工物理模型试验对整治线宽度进一步修正。
英文摘要:
      The determination of the width of the regulation line in the channel regulation is one of the key factors for the success or failure of regulation. In this paper,the calculation formula of the regulation width is improved on the basis of considering the stability of the navigation channel and the capacity of ships ascending rapids. Also,a formula for calculating the regulation width of the sand-pebble shoal in mountainous rivers is put forward. A mathematical model is established to verify and optimize the regulation width calculated by the formula in this paper through an engineering example. The calculation of regulation width is systematic work,the regulation widths calculated by the traditional formula,and the formula in this paper can only be used as reference values. To achieve a good regulation effect,the regulation width needs to be further modified by the mathematical model and physical model experiment.
