| Abstract: | The burying depth of JinPing secondary hydroelectric station is deep and the geo-stress is high. In the execution of TBM, rock explosion, caused by high geostress, arose, which had a huge influence on the construction schedule, equipment and staff. The paper summarizes the pattern of rock burst in the execution of TBM and explores the pattern as well. On the basis of experiments with different forms of support, preliminary knowledge of major burst is obtained. |
