【摘要】 通过分析预应力混凝土连续梁施工后的残余徐变的主要影响因素,从预测应力布置及梁体上下缘恒载,二期恒载施工时间,不同梁段施工周期,工后残余徐变预留调整4个方面提出了设计措施,并得出一些有现实指导意义的结论。更多还原

【Abstract】 Through analyzing main factors influencing residual creep after prestressed concrete continuous beam construction,it proposes design measures from aspects of prestressed layout and beam up and down eternal loading,second-phase eternal loading construction duration,different beam section construction duration,and after-construction residual reservation adjustment,and obtains some modern guiding conclusions.更多还原
