SCALE MODELING METHOD OF SHAKING TABLE TEST OF DYNAMIC INTERACTION OF PILE-SOIL-BRIDGE STRUCTURE IN GROUND OF SOIL LIQUEFACTION
液化场地桩-土-桥梁结构动力相互作用振动台试验模型相似设计方法

Nowdays,scale modeling shaking table test is an important method to study aseismic ability and destroyable mechanism of engineering structure. The design of scale model is one of keys to insure that shaking table test can really reflect the dynamic characters of prototype. In order to solve the similitude problem of shaking table scale modle test of dynamic interaction of pile-soil-bridge structure in ground of soil liquefaction,based on the theorem of Bockingham p widely applied at present,the dimensional analysis method is used,and the constitutive strain-stress relationship of material between model and prototype and the dynamic response similarity of pile-soil interface are considered at the same time. Finally the method is put forward to solve artificial mass problem.
