[0029] The present invention is illustrated below with a certain arch dam model test, the size similarity ratio of this arch dam model test is 250, the elastic modulus similarity ratio is 250, and the f similarity ratio is 1; each part distribution of the barite powder cemented novel rock mass similar material Ratio: The basic mass ratio of barite powder, bentonite and diluted glue is 12:0.3:1. The method of using barite powder to cement rock-soil similar materials and making simulated rock mass in this embodiment includes using shear test to determine the water-binder ratio of diluted glue, using uniaxial compression material test to determine the density-elastic modulus curve of similar materials, Calculate the water-binder ratio and wet density of the simulated materials for each part of the model, and make 4 parts of the small block specimens that simulate the rock mass.
[0030] The arch dam prototype and model test data of the present embodiment are as shown in Table 1: ...
