摘要
UHPC-NSC组合式盖板涵能够在不明显增加结构造价的情况下,提高结构抗裂性能,并适应更大的跨度和填土高度;给出了考虑收缩徐变影响的组合式盖板涵设计方法,针对不同填土高度对盖板涵截面形式进行优化,考虑了土拱效应出现的条件,给出了填土高度2~10 m时的盖板涵标准化设计。
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.
