| Abstract: | The general finite element software ANSYS is used to analyze the stress in deck paving on a continuous beam bridge with cross section of separated box-beam.The waterproof adhesive layer of synchronous chips is employed in deck paving. The worst load position is found out by discovering the stress on the waterproof adhesive layer,and the affection laws of the tensile stress and shear stress between the various layers caused by the longitudinal gradient of the bridge deck are analyzed and obtained. |
