赵家沟大桥系杆锚固区局部应力分析

Local Stress in Anchorage Zone of Zhaojiagou Bridge

考虑锚垫板、喇叭套管、螺旋钢筋与锚固区混凝土的相互作用和混凝土非线性特性的影响,采用通用有限元方法分析了双提篮系杆拱桥临时系杆拉力作用下锚固区局部应力。

The local stress and stress concentration in anchorage zone of Loshse bridge with four inclined ribs under tension force of temporary ties in construction were investigated. The nonlinear behavior of concrete and influences of base plate, tapered tube and spire reinforcements was considered in the analysis.
