Theory Study on Similitude Design of Shaking Table Tests of Earthquake-Induced Landslide
Based on analysis of characteristics of earthquake-induced landslides and summary of main factors of controlling earthquake-induced landslides, three main factors which are seismic parameters, topography and landforms features and engineering properties of soil are considered the main factor affecting on earthquake-induced landslides. These factors should be focused on to meet the similitude ratio design of the dynamics of landslide in Shaking table test design. Based on study of dynamic similitude law of landslide, the method of changing model soil specifications is used to prepare the model soil which is in accordance with the maximum shear modulus of prototype soil. Also, the engineering properties similitude of model soil is checked by the method of shear wave velocity similitude. By taking the theory of vibration behavior theory of similarity and dynamic failure similar, the formula of dynamic parameters similitude ratio was got. This formula provides calculating methods using shaking table test to simulate earthquake induced landslide.
