... often exist in deep rock mass with high stress, so that their mechanical deformation properties are often non-linear, ductility and nonuniform. The modeling and application of discrete element method in geotechnical engineering have undergone a relatively mature development, since itwas initiatively...

... on the influence of the rock mass strength. But the fitting algorithm is aimed at the maximum and minimum effective stresses, for some applications, this process cannot be gained the shear strength of rock mass under the condition of normal stresses. So the shear strength of rock mass of nonlinear equation...

..., the author developed the Rock Engineering Systems (RES) approach in 1992 and, in the 20+ years since then, the RES approach has been used for a wide variety of rock engineering and other problems. As a result, there are now many case studies available which illustrate the application of RES to rock...

... the system to be functioned without any repair since the sensors can detect a rock fall without any contact with rock. Reliability of this system was checked out through various tests both in a laboratory and in a field. The test results showed that the system was effectively applicable to detecting rock...
