Abstract

The rockburst prediction results of a tunnel in the Lhasa−Linzhi railway cannot meet the actual situation on site by applying the existing criteria directly. In order to formulate the rockburst intensity classification scheme and stress criterion for the whole line of the Lhasa−Linzhi railway, the measurement of the wall stress after tunnel excavation, point load test on rock samples and the excavation simulation based two-stage back analysis of initial geostress field were carried out based on the in-situ rockburst development characteristics and rules, rockburst failure trace in Sangzhuling tunnel of the Lhasa−Linzhi railway and kNN (k-nearest neighbor classification) algorithm, and then the rockburst intensity classification scheme and stress criterion for the Lhasa−Linzhi railway were proposed. After the verification of the prediction accuracy of rockburst in the Sangzhuling tunnel, the criterion was applied to the rockburst prediction of typical rock burst tunnels (the Zhulagang tunnel, the Dagala tunnel and the Gangmula tunnel) of the Lhasa−Linzhi railway, and the results are compared with the existing ones. The results show that for the Lhasa−Linzhi railway, the Russenes rockburst criterion will underestimate the occurrence of slight rockburst, but it is better to judge moderate rockburst. The rock burst grade judged by the Wang Lansheng criterion mainly focuses on slight rockburst, and the actual moderate and strong rockburst grades are not correctly judged, which indicates that it is easy to underestimate the actual rockburst grade. The rockburst grade judged by the Guanbaoshu criterion mainly focuses on strong rockburst, and it is easy to overestimate the actual rockburst grade because it basically does not correctly judge the actual slight and moderate rockburst grade. The rockburst criterion of the Lhasa−Linzhi railway is equal to the Lu Sen criterion in judging moderate rock burst grade, and its accuracy rate of rockburst prediction results is higher than other criteria, which is more in line with the actual situation of the Lhasa−Linzhi railway.
