RELIABILITY AND DAMAGE SUSCEPTIBILITY EVALUATION APPROACH TO THE ANALYSIS OF ROCK SLOPE STABILITY

Inasmuch simple and cnvenience,the deterministic design method is broad used in project design,but it exists some reasonless perse.The reliability design method considers the discretization of rock parameter,so design is more consistent with project practive.How to decide the reliability level becomes a key problem.This paper concerns damage risk analysis,ensuring the safety and considering the cost least of project,educes the reliability level used in possibility design method.
