摘要
高速铁路是指运行速度在200km．h^-1以上的铁路。高速铁路要为列车的高速行驶提供一个高平顺性和高稳定性的轨下基础，因此路基作为轨道结构的基础，必须具有强度高、刚度大、稳定性和耐久性好，并能抵抗各种自然因素的影响等性能。高速铁路的出现对中国传统铁路路基设计、施工、养护维修提出了新的挑战，在许多方面影响和改变了传统的设计观念或思想。
For travelling safely and steady,the high-speed railway subgrade must has high strength and rigidity.But in the construction of subgrade,the quality control is very difficult.According to the design and construction experience of high-speed railway subgrade at home and abroad,the quality control technologies are discussed,which can provide reference to the technicians engaged in high-speed railway construction.
