| 摘 要： | 指出桥式的布置首先要慎重确定桥梁的跨度,特别是主梁跨度,为此提出了一种以结构造价为目标函数,优化桥梁主跨跨度的简便方法,将该方法应用于桥梁的初步设计中,对于桥式方案的遴选、加速设计进度以及校核设计结果都有重要的实用价值。

| Abstract: | It points out that the first step to arrange a bridge style is to determine the span of a bridge,especially the main span.An optimal model of the main span length is established,and the cost of the model is taken as its objective function.This convenient method can be applied in preliminary design and selection of bridge styles.It can also increase the pace of design,and it has practical value for the evaluation of the results. |
