| Abstract: | In recent years, curved skew bridge structure is applied widely with the rapid development of highway, city road and interchange. Therefore, this paper analyzes the basic theory, internal force factors of the single span skew girder combining with an engineering example, and it establishes a unified expres- sion aiming at all kinds of force analysis so as to promote the application of this structure. |
