摘要
依托福建省交通厅海域混凝土防腐课题试验数据,拟合出福建海域大气环境混凝土腐蚀规律模型,并分析公路桥涵设计规范中刚度计算公式的不足,提出针对福建地区海域大气环境下钢筋混凝土桥梁刚度计算修正系数.
Relying on the test data of research proj ect of Fuj ian Provincial Department of Transportation about concrete anti-corrosion in sea area, the model of atmospheric corrosion of concrete in Fujian sea area was fitted.The shortcomings of stiffness calculation formula in highway bridge regulation are analyzed;and the modification coefficient of stiffness calculation for reinforced concrete bridge specific to atmospheric environment in Fujian sea area is proposed.
