摘要
探讨了中等跨径梁桥的先简支后连续体系的受力情况与结构性能，提出了适用的先简支后连续结构体系，并针对工程实例进行优化比较．
The structural properties of median span beams bridges constructed by simply supported-continuous system are studied. And the applicable simply supported-continuous system is given. Some engineering examples are compared and optimized also.
