摘　　要：提出了运用最优化理论与方法进行缓和复曲线设计参数优化组合的全新思想,并据此建立了相应的目标函数和约束条件,并通过构建增广目标函数求其极小值。通过算例说明其寻找缓和复曲线设计参数最佳组合的良好效果,使缓和复曲线的设计更趋于合理、简化。The auther presents a new thought finding the best assemblage of design parameter for transition compound curve by the applications of optimize theory and method in this article, and establish object function and its restriction condition, minimum of objct function is gained by founding expanded object function. A example demonstrate its good effect. This make design work of transition compound curve more reasonable-and simpler.
