Abstract

The underground caverns that locate in high geostress are being excavated. The surrounding rock masses are prone to appear longitudinal splitting cracks and lead to brittle craze even failure, like rockburst etc, and endanger the safety of engineering. The test of brittle rock and simulation analysis are carried out to study the extension process of splitting cracks and the phenomena of split failure are obtained. The mechanism and conditions are discussed according to the special project phenomena. The results can supply some significant guidance to design and construction of similar engineering.
