【Abstract】 The geometric design thoughts of the highway slope and slant bridge is the main factor of influencing design and construction.In the paper,the geometrical arrangement form when the bridge is conditioned by the alignment,the characteristics,patterns,methods and influencing factors of geometric design of highway slope and slant bridges are proposed.Without increasing the difficulty of the design,the author puts forward to reach the aim of improving the alignment of highway by the bridge geometric arrangement.And the effect in the actual bridge construction is illustrated combined with the bridge design in Wangkui-Lingshan highway in Heilongjiang Province.更多还原
