在苏联的西西伯利亚,装配式路面板多铺设在刚性不足的垫层上,联结结构承受着很高的剪力作用,—14定型版没有考虑这样高的剪力。观察指出,在换算弹性模量低于E_0=20～40兆帕的砂垫层上,使用2～3年后,横缝联结结构即遭破坏,缝内填塞料被挤出,然后形成了错位变形。联结结构的受力除剪力外,还同时受到因板端挠度造成的弯
In western Siberia, the Soviet Union, the assembly of pavement slab laying in the lack of rigidity on the cushion, the joint structure is subjected to high shearing force, -14 stereotype version did not consider such a high shear. It is observed that on the sand cushion with E_0 = 20 ~ 40 MPa conversion, the joints of the transverse joints are destroyed after 2-3 years of use, and the stuffing in the joints is extruded and then the dislocation is formed Deformation. Coupling structure of the force in addition to shear, but also due to the deflection caused by the board side bend
