ABSTRACT
The overburden of tunnels and underground caverns has been increasing in recent years. As a result, rock-bursting phenomenon has become probably one of the major concerns for the stability of such structures. This study is concerned with the assessment of susceptibility of rock bursting problem in tunnelling. The authors present a method for such a purpose by extending an earlier method developed by the authors for tunnels in squeezing rocks. This method is compared with other methods proposed for the predictions of rock bursting in underground excavations and it is applied to some tunnels where rockburst problems encountered to check its validity. And then its several applications to some tunnels with great overburden and under constructions are given and discussed.
