The paper mainly describes the structure size and structural design features of Jinsha island bridge, and the bridge is calculated using the program for the main bridge for structural analysis and checking the various stages of construction. Calculation results showed that the main phase of the bridge operator stress state are to meet regulatory requirements, structural design is reasonable.%主要介绍了金沙洲大桥主桥的结构尺寸及结构设计特点，并采用桥梁计算程序对主桥进行结构分析和各施工阶段的验算，计算分析结果表明主桥运营阶段受力状态均满足规范要求，结构设计较为合理。
