摘　　要：山区桥梁具有高墩小跨径的特点,为满足高墩的抗推要求,将高墩和主梁固结是有效的方法。文中以某在建的斜坡型桥梁为工程实例,考虑不同的桥墩形式和不同桥墩进行墩梁固结的情况,通过有限元软件midas对墩梁固结前后桥墩的受力状态进行分析,得到中小跨径斜坡型桥梁墩梁固结前后的受力特性变化规律。High pier and short span are characters of bridges in the mountain slope area. In order to satisfy the anti pushing rigidity, consolidation of the pier and the girder is an efficient method. Taking a bridge in slope area for example, the finite element software midas is used to analyze the mechanical status of piers under different conditions. At last, several meaningful conclusions on mechanical prop erties of the piers of short and medium span bridges in slope areas are obtained.
