接触面的基底的倾角与接触面内摩擦角共同影响排土场稳定性，并且可基于二者

The inclination angle of the base of the contact surface and the internal friction angle of the contact surface together affect the stability of the dump, and it can be judged that the dump is in a self-locking or unlocked state based on the two values. In addition, the increase in the inclination of the dump The overturning moment of the superstructure increases, and the difference in the shape of the base causes the difference in the amount of deformation in different areas of the dump. The steep, curved, and narrow terrain will obviously affect the sliding rate of the slope.

The inclination of the substrate of the contact surface and the friction angle within the contact surface together affect the stability of the drain site, and the drain site can be judged to be in a self-locking or unlocking state based on the size of the two values, in addition, the increase of the base inclination of the ground drain field leads to an increase in the top structure tipping torque, the difference in substrate morphology results in differences in the deformation of different areas of the drain site, steep, curved, narrow terrain will obviously affect the slope sliding rate.

The inclination angle of the base of the contact surface and the internal friction angle of the contact surface jointly affect the stability of the dump, and the dump can be judged to be in the state of self-locking or unlocking based on the value of the two values. In addition, the increase of the inclination angle of the waste dump base leads to the increase of the overturning moment of the upper structure. The difference in the shape of the basement results in the difference of the deformation in different areas of the dump The sliding rate of slope is obviously affected.<br>
