| Abstract: | Through access to a large number of literatures,this article summarized the general characteristics for common cracks of corbels,and with an urban overpass engineering as the example,it used the standardized checking methods for the structural checking of its cantilever corbels,while using the finite element method to conduct the corbel stress analysis,and in combination with the corbel cracking morphology seen during field testing,it studied the crack generation mechanism at corbel chamfer. |
