( 1 ) based on the experiments , this thesis discusses the stress loss of vertical prestress caused by deformation of anchorage , the resilience of the tendon and the joint compression ( l2 ) , the elastic compression of the concrete ( l4 ) and the relaxation of the tendon ( l5 ) . it is concluded that the anchorage deformation is dominated in vertical stress loss . measures are suggested to diminish the loss of the vertical prestress during the design and construction of the bridge ( 1 )本文在试验的基础上,研究了竖向预应力筋的锚具变形、钢筋回缩和接缝压缩损失l2 、混凝土的弹性压缩损失l4和力筋的应力松弛损失l5 ,其中,第一项是最主要的损失,论文据此对设计和施工中如何减小竖向预应力的损失提出了自己的看法和建议。
