摘要
针对目前强度折减法所使用的三个失稳判据的不足,提出了以塑性应变的突变性作为失稳判据的方法,分析结果表明,该方法合理可行,为边坡的稳定性分析提出了新的失稳准则,从而促进边坡的稳定性研究。
Aiming at three destabilization criterion shortage of present strength reduction method, the method with plastic strain as destabilization criterion was proposed. The analysis result indicated that the method was feasible, which provided new destabilization criterion for slope stability, therefore promoted slope stability study.
