模糊数学在立交匝道线形优化设计中的应用

将模糊数学的概念、原理应用到立交线形优化设计中,以立交平面线形设计中的2种基本线形—圆曲线、缓和曲线作为构成立交线形设计中的线形元,并且考虑了行车条件、线形几何约束、超高要求等约束条件,以及影响参数取值的因素的模糊性,提出了比传统的优化设计方法更为科学、合理的模糊优化设计方法,建立了模糊优化数学模型,并分析了其解法.

Application of Fuzzy Mathematics to Alignment Optimization Design of Interchange Ramp

Applying the conceptions and principles of fuzzy mathematics to the alignment design of interchange ramp,the circle curve and relaxation curve was considered as alignment units which constitute interchange alignment.The driving condition,alignment geometry,superelevation and fuzziness of the factors that influenced the determination of the parameters were considered too.A fuzzy optimization design method is put forward which is more reasonable than traditional design methods.The fuzzy optimization model and its solution are established.
