The authors proposed previously a method for evaluating rock mass slope stability by using the remote sensing on the ground. The method is based on the observation of the spectral reflectance (Lab value) and temperature of the slope surface. From the observed data, we estimate the seismic wave velocity and the ultrasonic wave velocity of slope surface, and evaluate the slope stability by using the conventional and empirical relationships. This paper applies the method to a lot of rock mass slopes, and verifies that the method can be applied effectively to various types of rock slopes.
