摘要
根据工况合理简化了112 m 钢桁梁浮托架设的临时支架及滑道计算模型，经检算满足现场实际。通过地基加固、支架受力分析及控制方法，对临时墩以及基础进行检算，并采取相应施工措施，从而使临时支架及滑道达到了钢桁梁拼装及浮拖施工要求。
The calculation model of the temporary support and slipway of 112 m long steel truss girder is reasonably simpli-fied according to the working conditions.Based on foundation reinforcement,support force analyzing and control method, checking calculation of temporary pier and foundation is made and corresponding construction measure is taken.Then the construction requirement of assembling and float dragging of steel truss girder for temporary support and slipway is met.
