摘要
Taking the excavation and reinrorcemeni of an unstable slope as an example,the slope stability is analyzed firstly in this paper by boundary element method (BEM) combining with limit equilibrium method (LEM). The changing response of safety factor Fmin of slope is known,and tke relation between Fmin and h, slope altitude, Fmin =ahb is drawu. Considering the relation between Fmin, and developing stages of sliding,dynamic stability state of sliding evolutiou is achieved. Based on the above results and in-situ monitoring information, the deformation laws are analyzed,and the slide duration (if not reinforced ) is forecasted successfully by unlted GM (1, 1 )-Verhulst grey model ror the purpose of guiding the correct reinforcement.
