大跨径连续刚构桥加固后荷载试验研究
Load Test Research of Long Span Continuous Rigid Frame Bridge after Strengthing
【摘要】 利用Midas/Civil对某桥进行结构计算,结合某大桥加固后的实际情况,进行了动静载试验,分析桥梁结构在荷载作用下的应力、挠度、结构的自振特性及在试验荷载作用下的动力响应,确定桥梁的承载能力是否满足正常使用状况的要求,评价桥梁加固效果。
【Abstract】 Midas/Civil is used to do structural analysis of bridge. According to the actual situation of a bridge after strengthing,dynamic and static load tests are carried out. The stress, deflection, natural vibration characteristics and dynamic response of bridge structure under loading are analyzed, the bearing capacity of the bridge are determined whether meets the requirements of normal service conditions or not, and the strengthing effect of bridge is evaluated.
