STOCHASTIC METHOD BASED EVALUATION OF CORROSION ROCK STRENGTH PARAMETERS

The present paper proposes an evaluation of corrosion rock strength parameters approach to analyze the corrosion calcareous rock strength parameters. The parameters are obtained through laboratory and in situ tests and cannot apply to the engineering directly. The proposed approach utilizes a numerical model in conjunction with the distribution of corrosion. It is based on site investigation to analyze the strength parameters of the corrosion rock. The relationships between strength parameters and corrosion are determined. In the meantime, laboratory triaxial tests are carried out. The results show that the relationship built on the numerical model is correct.
