The problem being solved in this paper is the three-dimensional stability analysis of rock block, separated by two sets of geologic structural surfaces from rock mass and loaded by a force system without common point of the action of forces. Some theoretical aspects, such as the principle of the nodal equivalent forces and the principle of block stability in terms of virtual work are discussed, and a mathematical method based upon the above mentioned principles is developed to obtain a general solution of the stability of rock block for various possible modes of its instability. The analysis of a series of practical examples indicates the reliability of this theory and method, and the capability of the computer program.
