路桥过渡段搭板受力分析

Structural Analysis on the Approach Slabs between Pavements and Abutment

应用有限元法，对路桥过渡段模型搭板在轴载作用下的受力情况进行了分析。分析中包括了搭板的几何尺寸、材料因素、地基非均匀、枕梁及沥青加铺层对搭板弯拉应力及变形的影响。

In this paper, finite element method is employed to analyze the mechanical behaviors of approach slabs between bridge abutment and pavements subject to axle loadings. The influence of geometric size, material properties of the slabs, inhomogeneous subgrade, sleeper beam and bituminous overlay on the bending stresses and deflection is investigated.
