| Abstract: | Through in-situ comparative experiment about the mechanic control index of railway foundation compaction and the statistical analysis of experiment results,the relation between the foundation index K30 and modulus of deformation Ev2 and the relation between modulus of deformation Evd and modulus of deformation Ev2 are found out.The differences and similarities of foundation index K30 and modulus of deformation Ev2 are analyzed and corrections for the foundation index K30 are proposed for reference of revise of relevant railway foundation specification and standard. |
