Device used in model experiments to test soil dynamic shear modulus

The invention discloses a device used in model experiments to test soil dynamic shear modulus. The device is suitable for both 1g model experiments and centrifugal machine model experiments and comprises a model box 100 similar to a to-be-simulated stratum in spatial size and a shear wave generating device 200 providing shear power for the experiments, a horizontally-placed shear wave generator 3 is arranged at the bottom of the model box 100 which is filled with corresponding experiment soil 110, and more than one acceleration meter is arranged at different heights of the experiment soil 110 hierarchically. The device can conveniently test shear modulus of soil layers at different heights, thereby providing basic parameters for strata vibration studying. 本发明公开了种用于模型试验中土体动剪切模量的测试装置。既适用于1g模型试验又适用于离心机模型试验。具有与拟模拟的地层空间尺寸相比拟的模型箱100和为实验提供剪切动力的剪切波发生装置200；模型箱100的底部设置有水平放置的剪切波发生器3；模型箱100内充填相应试验用土110，在试验用土110的不同高度上分层设置有个以上的加速度计4。本发明装置可便利地测试不同深度处土层剪切模量，为地层振动研究的进行提供基础参数。
