| 摘 要： | 为综合考虑高速公路构造成本和运营成本,详细分析了土石方成本和燃油消耗成本的影响因素,描述了土石方量和燃油消耗量的计算过程,以两者之和构造了适应度函数.然后对等距划分纵断面的变坡点进行二进制编码,基于遗传算法建立了一般情况下高速公路线路纵断面节能设计的模型与算法,致使线路设计的着眼点不再局限于强调工程造价的构造阶段,而是...

| Abstract: | With comprehensive consideration of both earthwork cost and fuel consumption cost,the influencing factors and the calculation procedures related to them were analyzed and described,and the sum of the costs was defined as the fitness function.Subsequently,slope changing points arranged uniformly in location were binary encoded as a chromosome,hence the model and algorithm of freeway's energy-saving vertical profile in general case was proposed based on genetic algorithm(GA),which lead to the designer focusin... |
