Based on the methods of finite element analysis,the comparative analysis of these two cable-stayed bridge schemes about static performances,dynamic performances,stability and wind resistance behavior were carried out. The results showed that it was feasible to form a highly efficient,durable concrete cable-stayed bridge with RPC girders and CFRP cables and made its applicable span range expand to 1 000 m long around. 关键词：混凝土斜拉桥 CFRP 斜拉索桥 PC梁跨度预应力碳纤维增强聚合物活性粉末混凝土
