![]() On the one hand, with the increase of loading rate, the peak strength of the soft-hard interbedded rocks decreases first and then increases The proportion of hard rock is positively correlated with the compressive strength of rock samples. ![]() The results show that the loading rate and the volume ratio of hard and soft rock are the main factors affecting the peak strength, while the loading rate and the thickness ratio of hard and soft rock are the main factors affecting the final failure characteristics. Under uniaxial compression, the effects of different static loading rates on the mechanical and acoustic emission characteristics of rock samples with different thickness ratios and different rock formation combinations were explored. ![]() Based on the measured data of sandstone mudstone interbedded rock mass in the Three Gorges Reservoir area, the soft-hard interbedded rock samples were made. ![]()
