摘要
运用通用有限元软件ANSYS对一座现有分离式箱梁截面连续梁桥进行桥面铺装应力分析。桥面铺装采用同步碎石防水粘结层。通过对防水粘结层拉应力、剪应力的计算找到荷载的最不利位置,分析荷载最不利位置下桥面纵坡变化对桥面铺装各层层间拉应力、剪应力的影响规律。
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.
