预应力连续T梁静动载试验及结构评定

On static and moving experiments of prestressed continuous T-beam and its structural evaluation

通过预应力连续T梁进行静动载试验检测,并应用桥梁专用软件midas civil进行有限元模拟计算,将试验结果的实测值与模拟计算得出的计算值进行比较分析,结果表明:该桥的强度和刚度均满足设计和使用要求,以不同的车速跑车、刹车作用时,没有发现动应变急剧增加的现象,说明桥面总体较平顺。

The paper undertakes the static and moving experiments of the prestressed continuous T-beam, undertakes the finite element simulation calculation by adopting the bridge special software, midas civil, undertakes the comparison and analysis of the calculation value between the measured value and simulation calculation of the test result, proves by the result that the strength and the stiffness of the bridge can meet the de- sign and application requirements, and indicates the bridge deck is generally smooth without sharply increasingly dynamic strain for vehicle at va- rious speed and braking role.
