摘　　要：栈桥是受地震作用明显的结构,通过对栈桥的结构工作特点分析,并建立三个不同模型进行地震作用计算比较。提出了栈桥从截面布置、跨度和支架布置等方面优化设计方向。最后通过实际设计案例表明优化方案经济效益明显。A trestle is a structure obviously affected by the earthquake function. With the analysis on the working features of the trestle structure, three different models established were applied to the calculation and comparison of the earthquake function. The optimization design orientation on the sectional layout, span, support layout and others of the trestle was provided. The actual design cases showed that the optimized plan could have obvious economic benefits.
