Abstract: The single-beam and simple strut oblique bridge was used to analyse the character of bearing force, and the formula for internal force in oblique beam was conducted. According to analysis and research, moment of turn on oblique beam of oblique bridge was less than that on ridge purlin of ridge bridge in thesame span. With reducing of angle , the value of moment of turn on oblique beam span reduced. According to the characters of moment of turn on oblique beam coupling reaction, the box section that had more resistant ability on moment of force was better.
