摘要
本文通过对吉舒线牛亡牛河大桥混凝土桥梁的实测并用 Miner线性损伤理论对其进行分析 ,得出了混凝土桥梁在正常运营条件下疲劳寿命一般不受控制 。
Based on site measurement,this paper makes an analysis to the concrete beam of Mang Niu He Bridge by Miner's theory,with the conchision as:the fatigue life of concrete beam is not influenced under normal conditions,while attention should be paid to the fatigue crigin due to reigforcement corrosion.
