摘要
Abstract
The development and research status of concrete subgrade structure of high-speed railway are reviewed from the aspects of engineering application,theoretical model,influence factors of dynamic and static properties,advantages and disadvantages of the common subgrade structure styles.Common subgrade structure forms are introduced in detail,and various subgrade structure forms are compared.In the study of vehicle-track interaction and dynamics,the research progress of vehicle-track vertical unified model and the the development of spatial coupling model and corresponding dynamics model are described.The future research of subgrade structure is also proposed.关键词
