High iron powder soil dynamic modulus decay

摘要

Transportation industry booming in recent years, the traffic infrastructure construction in full swing, Especially China expressway and high-speed railway construction achievements but also by leaps and bounds, More become a kind of typical traffic technology export overseas with Chinese characteristics. High speed railway high speed, high density, high safety and ride comfort characteristics, plays a vital role in high railway. As high railway base powder soil play a vital role in among them, Powder soil foundation built on transport infrastructure in the run-time prone to all kinds of diseases under traffic loads, in railway or highway and other infrastructure can't normal service. By under cyclic loading is high rail base in the research of modulus decay process of silt, avoid all kinds of diseases.
