Abstract：Based on the similarity theory，a mechanical model of consequent rock slope is established. The design idea and method of the explosion model test are introduced. Using detonating cord as the explosive sources，the deformation and breakage pattern of the archetype slope under near field seismic loading are studied and the effects of the retaining structure are estimated with underwater explosion model test. The test results show that the major deformation pattern of consequent rock slope near field seismic is interlayer sliding in jointed rock mass. The breakage pattern is sliding and fracturing caused by elastic wave. The distribution of the peak compressive stress of the gravity retaining wall is changed in different heights and presents bell-shaped distribution，which increases at first and then decreases. Test results and the in-situ investigation in Wenchuan after earthquake show that the retaining structures play an important role in the stability of slope.
