DEVELOPMENT OF LARGE-SCALE LAMINAR SHEAR MODEL BOX
大型叠层剪切变形模型箱的研制

Shaking table test is an important method to study earthquake resistance of engineering structures. The design process of a large-scale soil laminar shear model box, which is indispensable in shaking table test, is described. The advantages and disadvantages of all sorts of the soil model boxes used in the shaking table test are compared. Based on the comparison and analysis of seismic response of the prototype soil deposit of semi-infinite free-field, a large-scale laminar shear model box, which can replicate prototype soil layer boundary conditions, is designed. The internal dimensions of the model box are 3 m in length, 2 m in width and 1.8 m in height. The model box consists of fifteen rectangular, laminar rigid frames can well simulate the boundary conditions of prototype soil layer. The developed laminar shear model box lays a finn foundation for the success of the test and can also be adopted in other tests for seismic geotechnical problems o
