摘要
基于茅草街大桥1∶20模型试验,研究主拱空钢管合龙后偏载、几何非线性和灌浆顺序对结构内力与变形的影响,将实测结果与仿真计算结果进行对比、验证,并对实桥施工提出建议。
On the basis of the 1 ：20 model tests for the Maocaojie Bridge, this paper makes a study of the effect of eccentric load, geometric nonlinearity and procedures of grouting on the structural internal force and deformation after closure of the the main arch vacant steel tubes of the Bridge, compares the measurements to the simulation calculations and verifies the calculations and also gives suggestion to the construction of the actual Bridge.
