| Abstract: | In order to analyze the local slope stability of the east side of the Qidashan iron mine,it is necessary to obtain the mechanical parameters of the slope rock mass.Therefore,three kinds of lithological uniaxial compressive strength and shear strength under natural and saturated water conditions,tensile strength,elastic modulus and Poisson’s ratio under natural conditions were obtained through indoor rock mechanics tests.Combined with Hoek-Brown method,Г.ΦИCEHKO method and empirical reduction method,the measured rock slope mechanical parameters were reduced to obtain reasonable and accurate rock mass mechanical parameters. |
