摘　　要：为探究巨厚冲击层下煤炭开采诱发路桥框架结构的沉陷规律,针对巨厚冲积层下路桥框架结构在采动过程中地基受挠动影响大、易失稳的实际问题,运用相似材料模拟的方法建立室内箱涵物理试验模型,研究了不均匀沉降条件下框架结构基底附加应力、箱体上表面的竖向位移、箱体侧墙挤压附加应力和箱体顶板和底板的内外表面上中轴线处x向附加应力的变化规律。In order to research the motion of road and bridge structure mining subsidence under thick alluvium,according to the problem of road and bridge structure disturbance of large,easy bucking under thick alluvium. The change law of frame structure base additional stress, the surface of vertical displacement, the side wall extrusion additional stress,and the top and bottom of the box on the Xaxis of additional stress of under uneven settlement is studied by box culvert physical model using similar material simulation test.
