摘　　要：介绍天津慈海桥的工程概况,分析慈海桥采用新型斜拉桥和摩天轮复合结构的设计构思,论述慈海桥主桥部分双层布置的建筑设计、桥梁线形和纵横断面等道桥设计内容,分析复合结构的支承体系、倒Y塔架、减震的悬挂结构、钢箱梁主桥结构和摩天轮等结构设计的核心内容,指出结构主要通过轴力体系传递荷载的特点。利用MIDAS软件对摩天轮和新型斜拉桥的受力特性进行分析。提出天津慈海桥需要解决的关键技术课题。The Tianjin CiHai Bridge is outlined. The design concept is analyzed, mainly explaining why the hybrid structure of new-style cable-stayed bridge with giant wheel is adopted in the Cihai Bridge. The key points of each specialty, including architecture, structure and road-bridge, are presented. The structural characteristics are studied; and it is found that the loads are mainly transferred by the axial force system. The giant wheel and new-style cable-stayed bridge are analyzed by using the midas software respectively. Main technical problems that need to be solved for the Cihai Bridge are pointed.
