摘要:
厂外道路纵断面优化设计是在平面线形已定的基础上,用数学方法优化纵断面线形,提高选线设计质量,降低工程投资.采用多项式曲线拟合能反映地面的起伏趋势,在反弯点附近利用最小二乘法拟合坡线,并根据约束条件调整变坡点的位置从而自动得到初始可行的纵断面方案.在初始纵断面方案的基础上,通过划分网格的方式实现了遗传算法在纵断面优化设计中的应用,为遗传算法中初始种群的选取奠定了基础.论文对某热电厂厂外道路的一部分路线进行了实例研究,用网格法与遗传算法对纵断面变坡点进行了联合优化,结果表明该算法优化效果良好,能为前期设计提供参考,减轻劳动强度,降低建造费用
Abstract:
On the basis of plane alignment, profile optimization design of the outside road of factory uses mathematic method to optimize the profile alignment, improve the quality of route alignment design, and reduce the project investment. By adopting polynomial curve fitting, the ups and downs trend in the ground can be reflected, using Minimum Two Multiplication Principle fitting beelines, where every two beelines intersect at a point, and these points could be regarded as grade change points of the profile. Adjusting these grade change points based on constraints helps get the initial profile project. The authors divided the area around each grade change point into meshes in the initial profile project, and realized the application of profile optimization design for genetic algorithm, which provides a foundation of selection of the initial population. This paper lays emphasis on studying a thermal outside road, using mesh and genetic algorithm in order to carrying out joint optimization on profile point of change of gradient. The result shows that the optimization effect is good, for providing previous design reference for designer and degrading labor of designer and cost of constructing
