Abstract
Combined deck arch bridge is a type of bridge that is using the deck arch bridge and continuous beam to share the load.This bridge has many benefits for its economical advantages as well as lager bearing abilities,smaller weight,etc.It is easy to resist the push force in the arch feet with prestressing which is good for a soft foundation.This paper discussed this type bridge with the background of Chuangye road bridge in Qingdao,conducted the relationship of parameter to the stress state,and analyzed the coaction of super-structure and foundation,the suitability of this bridge on the soft earth was proved.
