Embodiment 1
[0085] Embodiment 1: Embodiment 1 uses formula (11) to solve the ultimate external load of a jointed rock slope containing 2 rock blocks.
[0086] (1) Formulate calculation parameters for jointed rock slopes.
[0087] Figure 8 It is a schematic diagram of the geometry of the jointed rock slope in Example 1. The slope contains two rock blocks. Rock block 1 is rectangular in shape with a width of 1.0m and a height of 2.0m; rock block 2 is in the shape of a triangle with a height of 2.0m and a bottom width of 5.495m. There is a through joint between rock block 1 and rock block 2, and the inclination angle of the joint surface is 20°. The physical and mechanical parameters of slope materials are shown in Table 1. Centroid C at block 1 1 There is a horizontal leftward external force F acting on the place, and the purpose of this embodiment is to solve the limit value F of F c .

Embodiment 2
[0100] Embodiment 2: Embodiment 2 is to use formula (12) to solve the strength reserve coefficient of a jointed rock slope containing 6 rock blocks.
[0101] (1) Formulate calculation parameters for jointed rock slopes.
[0102] Figure 11 It is a schematic diagram of the geometry of the jointed rock slope in Example 2. The inclination angle of the bottom of this slope is 25°, and the slope contains 6 rock blocks. The geometric dimensions of each rock block are detailed in Figure 11 . The physical and mechanical parameters of the slope materials are shown in Table 3. Among the six rock blocks, rock block 1 is a fixed rock block and cannot move, and rock blocks 2 to 6 may undergo translation or rotation. The purpose of this embodiment is to solve the strength reserve coefficient of the rock slope.
