| Abstract: | The composite slab culvert composed of ultra-high performance concrete and normal strength concrete(UHPC-NSC)can improve the structural crack resistance and increase the span and fill height without significantly increasing the structural cost.This paper gives a structural design method considering the effects of shrinkage and creep.According to the different fill heights,the cross-section form of the cover slab is optimized,and the conditions of soil arching effect are considered.The standard design of the cover culvert is given when the fill height is 2~10 m. |
