基于目标优化的大型通航隧洞断面尺度研究

Study on section size of large navigation tunnel based on objective optimization

  • 摘要: 通航隧洞是解决高山峡谷条件下通航建筑物布置难题的有效手段之一,其断面尺度设计受到多因素的制约。基于设计通过能力和船舶临界航速,建立了大型通航隧洞断面尺度目标优化数学模型。该模型以通航隧洞断面系数和隧洞宽度为目标函数,以设计通过能力和船舶临界航速为约束条件,结合工程实际情况将多目标优化问题转化为单目标优化问题,并给出目标函数的最优解。将提出的目标优化数学模型应用到构皮滩通航隧洞断面尺度分析中,计算结果与实际工程吻合较好,验证了模型的合理性和有效性。

     

    Abstract: Navigation tunnels are regarded as one of the effective ways to solve the layout problem of navigation buildings under the conditions of high mountains and valleys, and their section design is restricted by several factors. An objective optimization mathematical model for cross-sectional dimensions of large navigation tunnels is established in this study based on design passing capacity of navigation tunnels and critical ship speed. Section coefficients of navigation tunnels and tunnel widths are adopted as objective functions, while design passing capacity and critical ship speed are adopted as the constraints of the proposed model. And then, the multi-objective optimization problem of the proposed model can be transformed into a single-objective optimization problem according to the actual situation of engineering projects, and optimal solutions of objective functions can be solved based on the constraints. The proposed model is applied to the cross-sectional dimension analysis of the Goupitan navigation tunnel. The calculation results are in good agreement with the actual project, which verifies the rationality and effectiveness of the model.
