悬臂浇筑连续梁合拢段施工与计算
超级好看的图片摘要：合拢段施工是悬臂浇筑连续梁施工和体系转换的关键环节，梁体混凝土因昼夜温差的影响产生膨胀收缩，会造成合拢段新浇混凝土的开裂，影响混凝土的受力状态及悬浇梁体系转换的完成。合拢段施工必须采取科学合理的措施，设置必要的合拢刚性支撑锁定，使合拢段梁端保持相对固定，保证合拢段混凝土在凝固及工作过程中满足受力状态的设计要求，保持梁体线形，控制合拢段的施工误差。本文以笔者参与建设的南昌向莆铁路东新桥312#~315#墩（40+64+40）m跨富山大道连续梁施工为例，对悬浇连续梁合拢段的体系转换和预应力施工作了概述，并重点对中跨合拢段刚性支撑锁定作了简要的理论分析和设计验算。草原美景

关于新学期的名言三天旅游ersion complete. closure gment construction must take scientific and reasonable measures, t up necessary clod rigid support locking, so that the closure ction of beam end remained relatively fixed, guarantee of the concrete in the solidification and working process to meet the force status of the design requirements, keep the beam body alignment, control of closure gment construction error. in this paper the author participate in the construction of nanchang xiangpu railway east bridge 312 # ~ 315 # pier (40+64+40) m span continuous beam construction of toyama road as an example, on the cantilever casting of continuous girder and prestresd system conversion construction were summarized, and made brief theoretical analysis and design. with the key on mid-span closure gment of rigid support locking
