成型软岩填料路堤强夯补强现场试验研究
摘要:软岩的主要特点是粘土矿物成分含量高、强度低、性能不稳定、易风化、易软化、且易崩解,路用性能较差,在铁路、公路中的应用受限制。国内对软岩填料的工程性质认识不足,其填筑的铁路或公路路基,经多年运行后,在交通循环荷载作用或自然条件侵蚀下产生严重的路基病害。试验研究运用强夯法对成型软岩路堤进行补强,加强路堤填筑密实度以改善其路用性,检测证明其强夯效果显著。
Abstract:The main characteristic of soft rock is high element content, low strength, unstable feature, easy weathering and disintegration, poor adaption, which was limited on railway and highway. The stuffing's engineering character is not exactly understood, through the years' traffic circulation load or natural erosion,Serious disease will be caused by filling with stuffing's railway and highway road. This experimental research used dynanlic compaction for molding subgrade reinforcing, strengthened the density of the filled stuffing to improve its adaption, as a result, the dynanlic compaction's effect significantly after testing.
