螺栓扭矩增大，接頭區鋼軌軌腰拉力、夾板應力、螺桿內應力都會增大，而鋼軌位移會隨著螺栓扭矩的增大而減小。 -
A way to avoiding crack or reducing crack width of concrete or reducing distortion of member is using prestressed concrete. the writer tried to make full use of the merit of the prestressed concrete and designed prestressed concrete mandril to control crack of structure. the prestressed concrete mandril, which was firstly applied high pressure on a small concrete bar, and then was made in concrete, so it would act as reinforced bar and resist load. in this thesis the writer designed 24 mmnbers and had experimental study of them, reached the conclusion that the effect of resisting crack of the prestressed concrete mandril was good when the load was not large, it can enhance the capacity of resisting crack and reduce the crack distance and crack width, but when the loads was large, the effect of resisting crack was not good, when we used the prestressed concrete mandril and reinforced bar together in member, the effect of resisting crack was very good. the writer analysed the adherence mechanism and wreck mechanism of the prestressed concrete mandril in anxial tension members, and according to the character of the prestressed concrete mandril, the writer constructed the bond model of it. then the writer introduced the analysis theory of crack including the bond - slip theory, the non - slip theory, the synthesis theory and mathematics stat method. the different theory had different theory base, they considered that the primary affection of crack width was different. in this test, the crack distance and crack width of members which placed reinforced bar were match to the compute value of the code gb 50010 - 2002 very well. to the members which
本文共進行了24根試件的試驗研究，得出了預應力混凝土芯棒能較大地提高構件抗裂承載力，在荷載小於預應力混凝土芯棒的開裂荷載時有較好的抗裂效果，能較大地減小裂縫間距和裂縫寬度，但是當荷載較大預應力混凝土芯棒開裂時預應力混凝土芯棒的抗裂效果不是很好，若將普通鋼筋和預應力混凝土芯棒一起使用時則有很好的抗裂效果。本文分析了預應力混凝土芯棒在軸拉試件中的粘結機理和破壞機理，根據預應力混凝土芯棒本身的特點，提出了預應力混凝土芯棒與后澆混凝土之間的粘結模型。然後本文詳細介紹了經典的裂縫分析理論粘結滑移理論、無滑移理論、綜合理論和數理統計方法，各理論有著各自不同的理論基礎，認為影響裂縫寬度的主要影響因素也各不相同。 -
As the analysis shows that stress of the outside joint bar of rail is higher than that of the inner joint bar when a wheel rolls over the rail joint. furthermore the change of bolt tension has great effect to the stress distribution and stress level of all parts of rail joint
分析表明：接頭受力時，鋼軌外側夾板的應力水平比內側夾板的應力水平高；在受力條件相同的情況下，螺栓扭矩的變化對接頭各部件的應力分佈及應力水平有較大影響。 -
