Safety factor of the high rock slope excavation reinforcement significantly improved, but the earthquake has significantly reduced the slope factor of safety of all operating conditions, in line with the actual experience.

After digging up the rugged slope high quality factor, but markedly increased earthquake role significantly reduce the performance margin slope factor, and the actual experience.

After excavates the reinforcement this crag nature high side slope safety coefficient distinct enhancement, but the earthquake function obviously reduces under various operating modes the side slope safety coefficient, tallies with the practical experience.

Excavation safety factor of the high rock slope of strengthened markedly improved, significantly reduced under all conditions and earthquake safety factor of slope, consistent with the actual experience.
