摘　　要：根据交通功能和观光功能的需求,明珠大桥设计从人本主义出发,突破人车分行式桥梁采用结构分层设计惯性思维,将钢拱桥人行道在平面上以弧线方式与车行道分开。人行道桥亦是观景平台,既满足交通安全功能,又满足行人观光功能,是城市桥梁造型及功能上的一种创新。明珠大桥采用大型有限元计算程序建立三维有限元模型进行结构分析,主要包括静力分析、稳定性分析、动力特性分析、抗风分析、抗震分析等,计算结果均能满足规范要求。According to the demand of traffic function and sightseeing function,the design of Pearl Bridge is based on humanism,which breaks through the inertia thinking of hierarchical structure design of separate traffic bridges,separating the pedestrian pavement of steel arch bridge from the vehicle pavement in an arc way on the plane.The sidewalk bridge is also a sight viewing platform,which not only satisfies the traffic safety function,but also satisfies the pedestrian sightseeing function.It is an innovation in the shape and function of the urban bridge.The Pearl Bridge uses a large finite element calculation program to establish a three-dimensional finite element model for structural analysis,including static analysis,stability analysis,dynamic characteristics analysis,wind resistance analysis,seismic analysis,etc.The calculation results meet the requirements of the specification.
