中小跨空心板梁桥结构状态评估

Evaluation of structural state of medium and small span beam bridge with hollow slab

针对单跨16 m新沿江管桥空心板梁出现的较多裂缝病害,建立了ANSYS模型,对该桥首先进行了理论分析,然后进行了全面的普查并做了静力试验,根据新沿江管桥的理论计算、普查情况和静载试验结果表明该桥具有足够的强度和刚度,以保证行车安全。

In light of many crack damages appeared in hollow slab girder of 16 m single-span Xinyanjiang conduit bridge, the author builds AN- SYS model, carries out theoretical analysis on the bridge, does a general survey and static test, and shows, according to theoretical calculation of Xinyanjiang conduit bridge, survey condition and test result, that this bridge has enough strength and rigidity to ensure operation safety.
