高速铁路两构筑物之间短路基过渡段结构
摘要：
本发明公开了一种高速铁路两构筑物之间短路基过渡段结构，它包括过渡段路基，该过渡段路基铺设于两构筑物之间，两构筑物的间距≤60m，所述过渡段路基包括基床表层，该基床表层以下部分的过渡段路基填筑同一种材料，该材料为掺有重量百分比为3％～5％水泥的级配碎石。本发明的优点在于：当高速铁路两构筑物之间的距离≤60m时，采用本设计方案，两构筑物之间采用性能更好的掺有重量百分比为3％～5％水泥的级配碎石，不仅能抵抗构筑物距离过近带来的动响应叠加，且可实现构筑物之间的刚度和沉降平稳过渡。
摘要（英）：

The invention discloses a short roadbed transition section structure between two rapid transit railway structures, which comprises a transition section roadbed, wherein the transition section roadbed is laid between the structures; the space between the two structures is less than or equal to 60m; the transition section roadbed comprises a bed surface layer; the part, below the bed surface layer, of the transition section roadbed is filled with the same materials; and the materials are graded broken stones which is doped with 3-5% of cement in weight percentage. By adopting the design scheme, the graded broken stones with good performance are used between the structures, wherein the graded broken stones are doped with 3-5% of cement in percentage by weight, thus dynamic response superposition caused by excessively close distance of the structures can be resisted, and the stiffness and smooth transition of settlement among the structures can be realized.
