| Abstract: | The stability of high-speed railway embankment determines the comfort and security,so the increase in speed design makes a larger difference between a high-speed rail and an ordinary one,and the requirements on the roadbed become more stringent at the same time.Siltysand,as the special strata with low intensity,poor water stability and strong permeability,has brought great risks to the stability of high-speed railway embankment.This paper analyzes the basic mechanical properties of siltysand for Beijing-Sha... |
