In this paper, the strength characteristics, deformation characteristics and failure patterns of stratified sandstones at different angles with and without anchoring were studied, and the energy dissipation characteristics and energy transmission laws of stratified sandstones were obtained.The results show that the compressive strength of the anchored sandstone is greater than that of the anchorless sandstone, and with the increase of the stratigraphic angle, the compressive strength of the sandstone increases first and then decreases.The elastic modulus and Poisson effect of anchored sandstone are both smaller than those of anchorless sandstone, and the failure mode of anchorless and anchored sandstone is similar, and in the process of increasing the lamina angle of sandstone from 0° to 60°, the failure mode is changed from brittle cleavage failure to shear failure along the weak surface of stratigraphy;The dissipation energy of the sandstone with anchored sandstone is greater than that of anchorless sandstone with the same stratigraphic angle, and the anchoring effect improves the stability of stratigraphic sandstone;With the increase of the layer angle, the elastic strain energy and dissipative energy are shown to increase first and then decrease, the energy dissipation rate in the compaction stage is higher than the energy storage rate, and the energy storage rate in the elastic stage and the plastic stage is higher than the energy dissipation rate;The growth curve of the dissipative energy of anchorless sandstone is volatile, while the growth rate curve of dissipative energy of anchored sandstone is very volatile, and the growth curve is more sleek than that of anchorless stratified sandstone.
