  • 512 Wenchuan earthquake triggered thousands of rockcollapses,landslides,debris flows and other geological disasters. In order to study the response of the doublesides slope to the earthquake,we designed a total of 11 models according to the field investigation. We took four factors into consideration to study the seismic response of the slope. The four factors are the slopedegree,the top width of slope,structure combination and the shape of the doublesides slope. The tests manifested that (a)seismic inertia force is the main factor that results in slope failure; (b)the deformation and failure of the slope has a relation to the initial seismic direction; (c)the doublesides slope shows an conjugatedshear phenomenon; (d)different structure combinations of slopes result in different failure modes; e)the conjugatedshear phenomenon is more obvious on the laddershaped doublesides slope. The test findings are well in line with the results of field investigation.
