Introduction During the design and research in rock engineering, the common method to determine whether the rock damaged or not is as follows. firstly, calculate the state of stress of rock under certain loading, and then, determine whether the rock is failure or destruction based on the strength criterion.
Known from the previous engineering experience, the range and randomness of rock parameters could be expressed by the use of probabilistic statistical methods.
Reliability of rock engineering refers to the probability of rock remains without destroying under certain engineering conditions and within the specified time, therefore, rock engineering has become an important area of research and application of stochastic mechanics[1-2].
