| Abstract: | The different mechanics parameters of geostatic stress in the tunnel area can be obtained by the direct measurement of the in-situ stress in the drill holes using by the hydrofracturing method.Based on the results of geostress survey and synthetic study,it presents the stability degree of country rocks around the deep tunnel,tells and pre-estimates the possibility of breaking out a rock outburst during the tunnel construction,which can provide an important reference for the tunnel design.The technique has an obvious feature of a direct-viewing operation and better effects. |
