高墩连续梁桥满堂碗扣式支架施工安全控制研究与应用

满堂碗扣式支架具有整体拼装速度快、操作简单、整体性好、变形小等特点，在施工安全控制中，其承载能力与稳定性特别重要。通过在一座高速公路桥梁的施工监控中，根据现场受力情况建立力学计算模型，确定边界条件，使用桥梁有限元专业计算软件MIDAS与结构力学求解器计算对支架方案可行性进行了验算，然后在施工前进行了预压试验用以消除非弹性变形，在试验过程中采用新的测量方法进行了支架结构的变形量测，经过实测值与计算值对比确定了支架方案的可操作性。再在施工过程中再次进行监测，最终实现梁体混凝土的安全浇注。

Research and Application of Security Controlling of High-Pier Continuous Bridges Constructed with Full Framing Cuplok Holder

The construction method of Full Framing Cuplok Holder has been wide used in the con- struction of continuous bridges for it has the merits of fast assembling, simply using, good integer, and small deformation. It is very important that ensuring lording capacity and stabilization of holder when u- sing. Mechanical model and boundary condition of holder of a constructing bridge was established. As well it was solved by using professional calculating soft MIDAS and Structural Mechanics Solver. Then preloading experiment was done before construction, meanwhile a new measuring method was used. From the comparison between the theoretical calculating result and measuring result, usability of construction scheme was admitted. During the construction period, measuring was executed again. At last, concrete was casted safely.
