摘　　要：结合一铁路斜交刚构桥设计实例,通过对斜交刚构桥受力分析,提出斜交刚构桥在荷载作用下,刚臂墩和桩基上要产生一附加弯矩,简称"斜交弯矩",分析"斜交弯矩"产生的原因,并指出其特点,实例证明,"斜交弯矩"在斜交刚构桥设计中不可忽视。The combination of a oblique rigid frame bridge railway skew design example, through the oblique rigid frame bridge stress analysis made oblique rigid frame bridge under load, just arms embankment and pile on to produce an additional moment, referred to as ＂oblique moment＂ analysis ＂oblique moment＂ the causes, and point out its characteristics. From the examples proved that the ＂oblique moments＂ in oblique rigid frame bridge design can not be ignored.

关 键 词：斜交 刚构桥设计 荷载沿墩横向分布 斜交弯矩
