摘要
针对我国桥型选择中存在的主观性强、缺乏系统的评价,本文运用模糊综合评判法对桥型的选择做出了理论推导,同时考虑安全性、适用性、经济性、耐久性、美观性、环保性等方面对桥型选择的影响,建立隶属度矩阵,并结合工程实际,对连续梁桥、连续刚构桥、中承式钢管拱桥三种方案进行对比分析,得出备选桥型的评价分数值,选出适应于工程实际的桥型。
As for the phenomenon of subjective desire and insufficient systematic evaluation existed in the selection of bridge type, a theoretical derivation based on fuzzy comprehensive assessment method is established in this passage. Meanwhile, the influence of security, feasibility, economical efficiency ,durability, aesthetics and environment protection are considered and a membership function matrix was established. Then, the contrastive analysis in corporate with practical engineering based on the continuous beam bridge, continuous rigid frame bridge and half-through concrete filled steel tube arch bridge is carried out, so that the quantitative value of each alternative bridge type could be obtained, and the appropriate type is determined.
