| Abstract: | Liquefaction of saturated sandy soil subgrade causes serious damage for highway culvert. On the base of soil dynamic experimentation, through static-dynamic finite element analyses, it presents the trans-formation of subgrade with soil anti-liquefaction ability under the united action of highway roadbed and culvert substructure. And the influential factors of the highway roadbed stress are analyzed. |
