High-speed railway soft rock deep cutting roadbed long-term deformation blocking structure and design method
The invention discloses a high-speed railway soft rock deep cutting roadbed long-term deformation blocking structure which comprises flexible blocking structures arranged on the two sides of a roadbed at intervals in the longitudinal direction of a line, and the flexible blocking structures are formed by filling deep grooves excavated in foundation rock mass with flexible composite materials. The flexible composite material is formed by mixing polystyrene (EPS) foam particles, waste tire rubber particles and polyurethane resin (PU), the polyurethane resin (PU) is a cementing material, the polystyrene (EPS) foam particles and the waste tire rubber particles can be effectively cemented into a composite material with good compression resistance and tensile strength, and the composite material is also a waterproof material. Groundwater permeation can be prevented, a waterproof curtain is formed, and polystyrene (EPS) foam particles serve as coarse aggregate of the flexible composite material.
本发明公开了高速铁路软岩深路堑路基长期变形阻隔结构，包括路基两侧沿线路纵向间隔布置的柔性阻隔结构，柔性阻隔结构由地基岩体中开挖的深槽中充填柔性复合材料构成，柔性复合材料由聚苯乙烯(EPS)泡沫颗粒、废旧轮胎橡胶颗粒和聚氨酯树脂(PU)混合而成，聚氨酯树脂(PU)是一种胶结材料，能够将聚苯乙烯(EPS)泡沫颗粒和废旧轮胎橡胶颗粒有效胶结成一种抗压和抗拉强度较好的复合材料，同时也是一种隔水材料，可以阻止地下水渗透，形成止水帷幕，聚苯乙烯(EPS)泡沫颗粒作为柔性复合材料的粗骨料。
