一、实用意义在露天采矿和交通、水电、土建等岩土工程中,都存在着边坡问题。反映边坡稳定程度的主要力学参数是该边坡岩土自身在特定条件下的粘着力C、内摩擦角φ以及最小断裂面的抗拉强度σ_p。这些参数可通过现埸岩体弱面强度试验取得,在有滑体存在的情况下,也可通过滑体反算求得。根据滑体反算的C、φ、σ_p,在某种意义上说更具有代表性和实用价值。这是因为: 1.内因(岩土的物理力学性质、边坡角和工程地质情况)是滑坡的根据,外因(水、采矿、震动、外荷、时间等)是造 I. Practical Significance There are problems with slopes in surface mining and geotechnical projects such as transportation, hydropower, and civil engineering. The main mechanical parameters that reflect the degree of slope stability are the adhesion force C, the internal friction angle φ, and the tensile strength σ_p of the minimum fracture surface of the slope itself. These parameters can be obtained through the strength test of the weak surface of existing rock masses. In the presence of a slippery body, they can also be obtained through the inverse calculation of the slippery mass. The C, φ, and σ_p inversely calculated from the slippery body are more representative and practical in a sense. This is because: 1. The internal cause (physical and mechanical properties of rock, slope angle, and engineering geology) is the basis for landslides, and external causes (water, mining, vibration, external load, time, etc.) are
