水泥混凝土桥沥青铺装层病害成因有限元分析

the paper uses the finite element analysis model, has carried on the analysis to the shearing failure and the dehiscence destruction reason of the bridge asphalt pavement. In analysis process, by full considering the interior factor and exterior factor influence, has simulated in actual situation each kind of operating mode, finally discovered the basic reason which the flooring level shearing failure and the crack destroyed. The analysis result has the certain model significance to the pavement design and the construction.
