露天栈桥柱基纠编过程中柱顶约束反力的估算

Estimate method for the restraint reactions on the capital of trestle under open sky during column base re-aligning

提出了一种在吊车梁的约束存在条件下，进行柱基纠偏时利用实测位移量和顶升力来估算露天栈桥柱顶约束反力的方法。此法可用来估计纠偏所引起的构件内力，指导纠偏施工。

In this paper an estimate method by making use of the measured displacements and jack forces is put forward for the restraint reactions on the capital of trestle under open sky caused by columm base realigning when the beam restraints exist.It can be used to caculate the internal forces in the beams and shafts for this kind of trestles.
