After Wenchuan earthquake

evaluation of maximum aseismic capability of high earthrock dam is required in China.Till now the comprehensive and thorough evaluation is done from the perspectives of dynamic stability of dam slope

earthquake-induced permanent deformation

liquefaction safety

the stress state in concrete seepage structure

and so on

synthetically by both numerical method and physical model test

and this evaluation method is first applied in Changheba earth core rockfill dam project.Yet at present there are no uniform evaluation criteria

and the reason is found to be that numerical method and physical model test cannot fully simulate the reality

limitation of details of analysis method and earthquake damage information

and researchers′different understanding.New approaches are put forward to decrease the divergence of the criteria

for example

in slope stability analysis

the maximum thickness of the slope is stipulated to be no smaller than 5m

and in stress analysis of concrete cutoff wall

both the compressive strength and tensile strength should be considered

and relevant stress criteria is proposed.New criteria are suggested.
