Road Foundations To Determine Liquefaction, Liquefaction And Liquefaction Regional Study

On the base of discussion which associated with the reliability of highway substructure liquefaction estimation and the liquefaction preliminary decision, through soil dynamic experiments and static-dynamic finite element analyses, this paper studied the substructure soil anti-liquefaction raising ability which under the union action of highway embankment and the substructure.The paper had made the substructure soil liquefaction level decision formula which considered the stress of highway embankment, on the basic of final analyses results. It also divided the liquefaction zone of highway substructure.The paper propounded that according to the different liquefaction lever and the different zone, man should planed an applicable treatment method on the highway substructure soil anti-liquefaction resolution.
