1) stilted arch
上心拱
2) a stilted arch
[建]上心拱
3) stilted vault
上心拱形穹顶
5) camber
[英]['kæmbə(r)] [美]['kæmbɚ]
上拱度
1.
Study on the prestress concrete beam camber under different creep modes;
不同徐变模式下预应力混凝土梁上拱度的研究
2.
By analyzing measured value of the camber and theoretical value of camber of RPC low-altitude T-beam at the stretching stage,a comparison certifies that the pre-stress s stress is controlled accurately,and the loss of pre-stress is cal- culated correctly,which means the theoretical calculation method of camber is feasible.
对RPC低高度T形梁张拉阶段梁体上拱度试验实测值和理论计算值进行对比分析,两者符合较好,证明了该梁预应力张拉控制得比较准确,预应力损失的计算方法得当,上拱度的理论计算方法是可行的。
3.
Under the action of a prestressing force,the camber deformation of a PC simply supported girder develops slowly due to concrete creep effect.
如果对于徐变变形的预测不准,在运营阶段梁体徐变变形的发展将会引起桥面的立面线形不平顺,严重影响行车安全和旅客舒适度,甚至将造成梁体上拱度过大而无法使用。
6) creep camber
徐变上拱
1.
Based on the fact that the creep camber of the high-speed railway bridge should be carefully considered,a new-type twice prestressed composite structure applied to high-speed railway bridge was proposed.
针对高速铁路桥梁对于徐变上拱度有着严格的限值,若徐变上拱过大将严重地影响铁路桥梁的使用性能,甚至危及行车安全等问题,提出将新型二次预应力组合结构应用于高速铁路桥梁。
2.
Excessive creep camber of prestressed concrete bridge would result in risk on the traffic safety in high-speed railway.
高速铁路预应力混凝土桥梁徐变上拱过大会影响桥上列车运行安全,为了控制预应力混凝土桥梁徐变上拱,将2次施加预应力新技术应用于预应力混凝土梁中,以箱梁为例,设计了4根不同预应力度的2次预应力简支组合梁,分析了其各施工受力阶段截面应力、强度和抗裂性,并进行了结构尺寸与配筋完全相同的常规预应力混凝土简支梁和2次预应力简支组合梁徐变上拱的对比计算分析。
