Abstract:

Based on conditional probability evaluation method and systematic engineering theory, considering key block as the important part of blocks system, the evaluation method of reliability of key block was analyzed, then we discussed the inner-relationship between key block and secondary key block, and following the same thought, we knew the relationship between secondary key block and the following block easily, so it would be possible to establish the systematic blocks evaluation model if we had gotten the reliability result of each block. With the reliability evaluation formula of Series System, we could calculate the reliability of systematic block. The suggested method was applied to a hydropower project in Southwest China so as to test its reasonableness. The results demonstrated that it was more coincidence to practical situation of the engineering than traditional evaluation of key-block theory. It would have some extent reference for the research of systematic blocks theory.

Key words: rock mechanics, reliability of blocks, conditional probability, systematic model
