铁路下穿式结构施工受轮轨作用力的影响分析

Dynamic Analysis of Wheel / Rail Interaction During Construction of Tunnel under Railway

结果表明，SiC空心多孔泡沫陶瓷与390Al复合后形成了复式连通双连续相复合材料，具有独特的互穿式界面结构，材料界面的结合优异。

The results show that the structures of struts of SiC foam reinforcement have an important role within the composites . The double-interpenetrating SiC / 390AI composite reinforced by the SiC hollow and porous foam ceramic has unique interpenetrating interface , so the composite has the perfect interface bond .

所述的框架式结构体的上下面板的四个角落布有圆柱孔，圆柱孔内穿有将框架式结构体垂直固定的圆柱。

Cylinder holes are arranged at four corners of the upper and lower panels of the framework structure body and cylinders for vertically fixing the framework structure body penetrate the cylinder holes .
