摘要
同时考虑了几何非线性和材料非线性等因素对淳安南浦大桥进行结构内力分析 ,结果表明对淳安南浦大桥这种大跨 ( 30 8m)、宽跨比小 (接近 1/19.81)的钢管混凝土拱桥 ,几何非线性和材料非线性的影响均较大 。
Considering the factors such as geometric nonlinearity and material nonlinearity etc. the paper analyses the structural internal force of the Chun'an Nanpu Bridge. The result shows that for this kind of steel pipe concrete arch bridge with great span (308m) and small wide-span ratio (near 1/19.81) of Chunan Nanpu Bridge the influence of geometric nonlinearity and material nonlinearity is bigger, so while designing and constructing it should not be neglected.
