Based on the Structural Stability of Underground Engineering Rock Classification
Taking the hole and energy change as influencing factor,the constitutive property of rock was quantified. The principle and trial method for structure parameter of rock was provided,and then the rock around underground structures was rank in order of stability by using the structure parameter. The outcome verified that there is a good correlation between the structure parameter and existing evaluation methods,and also proved classification method of structure parameter rationality. Compared with the other method, using the structure parameter of rock to stability evaluate can determine a outcome of a more scientific, more rational and more operational.
