摘要
桥梁跨径组成与诸多因素有关,其中经济性是评价桥梁方案是否合理的重要指标。桥梁跨径组成的经济性就是使桥梁上、下部以及基础的总造价达到最低。通过对常见装配式桥梁进行不同标准跨径桥型方案的综合比选模拟比较,选定合理的桥跨方案。
The span composition of a bridge is related to many factors,among which economy is an important index to evaluate the rationality of a bridge scheme.The economy of bridge span composition is to minimize the total cost of the bridge,the lower part and the foundation.Through the comprehensive comparison and simulation of different standard span bridge types of common assembled bridges,the reasonable span scheme is selected.
