Abstract:

In order to investigate the dynamic properties of SRM under cyclic loading， the law of permanent deformation of soil-rock mixture （SRM） with two different particle size types， the evolution of hysteresis circle， dynamic elastic modulus and damping ratio development law of SRM under different reinforcement methods are investigated by large dynamic triaxial test. The experimental results show that the axial strain （ε）-vibration number （N） curve of the specimen under different dynamic stress amplitude is consistent with the shakedown theory and more in line with the hyperbolic model development law. The reinforcement effect significantly improves the dynamic stability of the SRM specimen； when the dynamic stress amplitude is larger， the occlusal friction effect of the SRM specimen mixed with large gravel（GL） is more significant than that of the SRM specimen mixed with small gravel（GS）， and the accumulated plastic deformation is smaller. As an inhomogeneous engineering material， the hysteresis loop shows a "sawtooth" shape at low cycle times during cyclic loading. Before and after 30 loading cycles， the growth rate of the dynamic elastic modulus of the geogrid-reinforced specimen increases， and the damping ratio begins to decrease from the unstable fluctuation. Comparing different reinforcement test data， the results show that the geocell reinforcement enhances the resilient and stiffness of SRM better than the biaxial geogrid reinforcement.

Key words: geotechnical engineering, reinforced soil-rock mixture, large dynamic triaxial test, hysteresis loop, dynamic elastic modulus, damping ratio
