Speech Title: Statistical Mechanics of Rock Masses -- A rock mechanics from engineering geology
Abstract: This is an IAEG Hans Cloos Lecture given by the reciepient of Hans Cloos Medal. The speech is to talk about the following issues:
1. Statistical Mechanics of Rock Masses (SMRM) is a rock mechanics from Engineering Geology, which reflects the mechanical effects of major geological factors of rock masses, with systematical theory for fundamental research and applicable techniques for engineering practice.
2. Four basic SMRM models have developed including geometric probability model for rock mass structure, stress-strain relationship model, strength & failure probability model and permeability model. These models have been extended used in calculation of point engineering parameters for rock mass structure like joint volume density and directional RQD, stress and deformation like elastic modulus and Poisson’s ratio of rock mass, compressive and shear strength and failure probability, directional permeability, and quality rating of rock mass, etc. Numerical analysis has been developed to obtain point cloud of these parameters mentioned above for engineering analysis. SMRM has also applied for analysis of rock burst, stability and active reinforcement of rock mass.
3. A set of application techniques and equipment have been developed including a backpacked laboratory for rock mechanical tests on site which could obtain the deformation and strength parameters of rock and frictional angle of joint; a software -- “SMRM Calculation” for parameter calculation and a numerical module -- “modelSMRM” for Flac3D-6.0 have been developed for engineering analysis.
