Abstract:

In petro-industry, mining, hydroelectric engineering, express way, rail way, and nuclear waste disposal, nonpenetrative fractured rock mass is one of the most important and common materials. The full understanding of fractured rock mass property is the first and the most important thing in order to know it, to use it, and to improve it. In most cases, failure mode of fractured rock mass is dominated to its property, so it is important to study and research it. Based on the failure mode and the structure of the fractured rock mass, which are critical for understanding its property and characteristics deeply are studied. According to the structure of fractured rock mass, the research results are achieved by the former scholars or drawn from literatures, studying methods, analytical perspective; the merit and the disadvantage of physical and numerical model tests and site experiments are discussed, the key issues in researching work are pointed out, and the solution plan is made out.

Key words: fractured rock mass, nonpenetration, failure mode, study status, summarization and review
