Strength Characteristics of Natural Rock Mass and its Engineering Application
All rock mass engineering projects are closely related to rock mass material property. The methods of obtaining these properties decides the project design’s safety and reasonable. The varied characteristics of rock mass under force are subjected by their texture, construction and tectonic history. The experimental results imply that the rock mass strength, deformation and failure modes are all effected by following aspects, including the test controlling method, machine stiffness and the sample size, etc,. In order to use the test results to guide the practice projects, we must first know the natural status and engineering propagation process of rock mass, then design suitable experimental scheme, subsequently, the more fit for the natural results of rock changed process will be appear. According to the analysis of previous research achievement and newly test results, we can investigate the rock mass stability and predict its failure.
