摘要
湖北恩施朝阳大桥为上承式钢管混凝土桁架拱桥.文中对该桥进行荷载试验检测,试验结果表明,其实测拱肋应力校验系数为0.79～0.96,钢管拱肋位移校验系数为 0.75～0.88,桥面板应力校验系数为0.75～0.83,桥面挠度校验系数为0.87,残余应变和变形小于20%,其结构承载力满足设计要求.
Abstract
The load test shows that the measured arch rib stress check coefficient is 0.79～0.96,the arch rib displacement check coefficient is 0.75～0.88,the bridge panel stress check coefficient is 0.75～0.83,the bridge floor deflection check coefficient is 0.87,and the resid-ual strain and deformation are<20%.Structural bearing capacity meets the design requirements.
