R/S Analysis for Stress Evolution in Shaft Lining and Fracture Prediction Method

Abstract:

The rupture disasters occurred in more than 110 shafts in Eastern China in recent 23 years, and that caused a significant economic loss. The stress evolution in shaft is investigated by R/S method based on in-situ measured additional strain caused by ground drainage in present study. The results indicated that the R/S method predicts the variation of additional strain well. The Hurst index for additional strain lies in the range of 0.5~1 and the sequence is random walk with positive skew. In other hand, the positive skew of stress in shaft is less evident at the depth of 120 m. The research proposes guidance for prevention similar shaft rupture disaster is provided for similar shaft.
