Abstract Loess is water collapsible and vulnerable under earthquake. Through laboratory testing study on the dynamics constitutive model，elastic modulus，damping ratio，seismic subsidence and liquefaction and field test on wave velocity and ground tremor of loess ground treated with dynamic compaction，the effect of dynamic compaction on the seismic resistance of loess ground is evaluated quantitatively. Accordingly，the technical criteria for combinative treatment of loess ground for seismic subsidence and water collapsibility are proposed.
