文摘

Liquefaction resistance of gravelly soil increase with increasing gravel content. Numerical simulation results can reflect the macro mechanics phenomenon of saturated gravelly soil liquefaction. Anisotropy is the most important mechanical properties of gravelly soil liquefaction. Both of the fabric and force-chain can reflect the deflection direction of the principal stress.
