Abstract :
From highway sub grade, this paper takes the dynamic finite element simulation method to simulate dynamic response of saturated silt roadbed under typical working conditions, takes analysis of the relationship between additional dynamic stress of sub grade and its liquefaction resistance, the ratio relationship between additional dynamic stress and its original effect, and influence of various main factors on stability of saturated silt roadbed.
