| 摘 要： | 合龙时实施顶推是优化矮墩及高温合龙连续刚构桥长期受力状态的重要途径。结合工程实践,探讨了对边主墩施加水平顶推力和墩顶侧向位移的计算过程,并详细介绍了顶推施工的控制指标。现场实测数据证明,预定的顶推力和墩顶位移设置合理,实测顶推力及墩顶侧向位移均在预期控制范围内。

| Abstract: | Loading pushing force before closure construction is an effective measures which optimize long-term effect of low-pier continuous rigid frame bridge closed on high-temperature.Combined with engineering practice,it has been discussed that the calculation process of pushing force on the top of the hypo-middle piers and horizontal displacement,and the control indicators of pushing implementing were introduced.Practical results showed that assumptive pushing force and horizontal displacement were appropriate an... |
