Strip-laying period cushion layer vibration reduction ballast bed
The invention discloses a strip-laying periodic cushion layer vibration reduction ballast bed which comprises a periodic composite ballast bed plate and a concrete base arranged below the periodic composite ballast bed plate, and the periodic composite ballast bed plate is formed by alternately arranging and solidifying concrete plates and periodic cushion layers from top to bottom; the periodic cushion layer is composed of at least one long-strip-shaped cushion plate which continuously extends in the driving direction, the width of the cushion plate is smaller than that of a concrete plate, the cushion plate laying range of the cushion layer in the same period does not exceed the concrete plate, and a cushion layer strip laying mode is formed. Projections of the periodic cushion layers located in the interlayers are completely overlapped, the periodic cushion layers of the adjacent layers are aligned in the vertical direction or arranged in a staggered mode in the transverse direction, and a one-dimensional or two-dimensional scattering type periodic structure is formed. The vibration reduction ballast bed can form elastic wave forbidden bands in the vertical direction and the transverse direction, vertical vibration propagation and transverse vibration propagation are effectively controlled, the forbidden band range can be actively adjusted by changing the geometric dimension and material composition of the structure, and adjustability is high.
本发明公开了一种条铺周期垫层减振道床，包括周期复合道床板及设置在其下方的混凝土基底，周期复合道床板由混凝土板和周期垫层由上至下交替排列固结而成；所述周期垫层由沿着行车方向连续扩展延伸的至少一条长条形的垫板构成，垫板的宽度小于混凝土板宽度，同一周期垫层的垫板铺设范围不超出混凝土板，形成垫层条铺形式；处于隔层的周期垫层投影完全重合，相邻层的周期垫层在竖直方向上对齐，或在横向上错位设置，形成一维或二维散射型周期结构。该减振道床可在竖直方向和横向上形成弹性波禁带，有效控制竖直方向和横向振动传播，通过改变结构几何尺寸与材料组成，能够主动调节禁带范围，可调节性强。
