| 中文摘要: |
| 连续刚构桥的合龙是该桥型施工中非常重要的工序之一。通过对某6跨连续刚构桥的多种合龙方案进行结构变形、内力对比分析，依据顶推方案的优选，确定了最佳的合龙方案，确保大桥线形及受力处于较为合理的状态，并为同类多孔连续钢构桥梁的合龙技术提供参考。 |
| 英文摘要: |
| The closure of continual rigid frame bridge is one of the extremely important working procedures in this bridge construction. Through contrasting and analyzing on the inter-force and distort of a PC continual rigid frame bridge with six spans which is closed under different closure plan,this article chooses the best closure plan based on the optimal pushing force choosing. Bridge alignment and force are in resonable condition using the closure plan. The research results could provide reference for the simil... |
