Application Introduction and Design Essentials of Hidden Bent Cap Small-box Beam for Viaduct
Based on a viaduct project in Zhengzhou,the following control conditions need to be met at a certain node,such as need to guarantee the distance between the foot of the ramp slope and the stop line at the intersection,trying to increase the length of the interwoven section on the viaduct,and doing the best to reduce the structural height of bridge on the premise that the type of the bridge structure is consistent with the standard section structure.On the basis of the above constraints,the design scheme of hidden bent cap precast small-box beam is proposed.The application of hidden bent cap precast small-box beam for the viaduct is introduced,and the design essentials hidden bent cap small-box beam are expounded,which provides the useful reference for the design of similar bridges in the future.
