Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] like figure 1 As shown in , a theoretical calculation method for the macroscopic shear strength of large-scale bedrock includes the following steps:
[0027] 1) Take out a cube containing enough specimen-sized rock masses from the large-scale rock foundation As a macroscopic characteristic unit of rock mass; define a rock mass as large as a sample as a small-scale rock mass characteristic unit;
[0028] 2) Determine the mean value of small-scale friction coefficients of small-scale rock mass characteristic units based on small-scale rock mass shear test data and variance mean value of small-scale cohesion an...
