连续梁支架承载力验算与施工

Bearing Capacity Checking of Support of Continuous Beam and Construction

以预应力混凝土连续梁桥为工程背景,对连续梁桥0号块现浇支架的承载力进行了验算,验算结果表明,钢管柱支架满足强度、刚度和稳定性要求,能够确保连续梁0号块安全施工,并提出了支架的施工工艺及控制要点,可为类似工程施工提供参考。

Based on continuous prestressed concrete girder bridge,the structure and bearing capacity of number 0 block of continuous girder bridge are introduced. The construction technology and control points of the bracket are also proposed. The results show that the steel column support meets the requirements of strength,stiffness and stability,and the safety of the continuous beam number 0 block construction is gotten. It can supply reference and advice with similar construction.
