Restricted by geography, it is unavoidable for a bridge to undercross the highway obliquely. Taking some bridge in Shen-Dan Highway for example, this paper introduces a new thinking of crossing. Through MIDAS modeling analysis, it is to get the force features of width diaphragm of continuous box girder bridge under oblique support and the relevant suggestion of design are given at last.%由于地形受限,桥梁不可避免地斜向跨越下穿高速公路,本文以沈丹高速某桥为例,介绍一种新的跨越思路,通过Midas建模分析,给出斜支撑下连续箱梁桥宽横隔梁的受力特点,并给出相关设计建议。
