Geostress Measurement and Rock Burst Prediction Analysis for a Deep-Buried Long and Large High-Speed Railway Tunnel

Abstract:

Rock burst is one of the main geological disasters in deep-buried long and large tunnels, therefore rock burst prediction is necessary to ensure the safety of tunnel construction. Measuring the geostress in Yaojia tunnel, and using the Turchaninov and Russenes to conduct comprehensive evaluation, it turned out that the maximum horizontal stress is 3.6~12.5MPa and the minimum horizontal stress is 2.1~7.8MPa in the surveyed area, the dominant direction of the maximum horizontal stress is about N34 W, the angle between the maximum horizontal stress and the tunnel axis is about 83°. And these results showed Yaojia tunnel may occur slight rock burst within 400m of its length and it is adverse to the stability of tunnel surrounding rock.
