NUMERICAL ANALYSES ON THE BRITTLE FAILURE OR ROCKBURST OF ROCK MASS INDUCED BY TUNNEL EXCAVATIONS IN VICINITY OF A FAULT
The extraordinary distributions of stress and displacement were studied under the conditions of four different factors in vicinity of a fault. Some principles were obtained to predict the occurrences of brittle failures or rockburst. The test designs of orthogonal and uniform methods were adopted in this paper to calculate sixteen engineering schemes using numerical analyses and some regular results were determined. Ultimately, some typical engineering cases were analysed to study the stability of the surrounding rock masses and the possibility of the occurrence of rockburst when the excavations approach a fault.
