【摘要】 重庆石板坡长江大桥为钢—砼混合连续梁与连续刚构组合体系。为保证桥梁成桥线形、内力满足设计要求,采用有限元法进行施工阶段结构计算,并对影响桥梁线形、内力状态的因素进行分析,为施工控制决策服务。更多还原

【Abstract】 Chongqing Shibanpo Yangtze River Bridge adopted the steel-concrete composite structure of the continuous beam and continuous rigid frame.For assuring the alignment and internal force to meet the requirement of design,we calculate the construction structure of the bridge by finite element method,and analyzed the factors which influenced the alignment and internal force of the bridge to serve the decision of construction control.更多还原
