The Road Foundation. Rigid Foundation Liquefaction Research

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