摘要

Inbetween the many factors, which will influence the distribution character of initial stress, the slope angle of the mountain is important one. Therefore, stress distribution in mountains under different slope angles with considering different lateral coefficients of initial stress is studied using numerical method. The results show that the actual initial vertical stresses are usually 2–5 times of the gravitational stresses for some zones. The next part of this paper shows the remarkably different plastic zones distributions after excavating a cavern under different slope angles. Ultimately, a suggestive advice to determine the fitting areas of the in-situ stress is proposed.
