摘要

针对边坡稳定分析中所采用的基于强度参数折减的有限元方法，提出利用温度场来控制强度参数的折减，大大提高了计算效率。两个计算实例表明，一定时步后?max / H，即节点最大位移对坡高的比值，会快速增加，建议取该比值在0.05～0.1之间的不收敛时刻或突变时刻对应的折减系数作为安全系数。

Abstract

The slope stability analysis has been performed by finite elements using strength reduction controlled by temperature field. The calculation efficiency has been obviously improved. From some case studies

?max / H

the ratio of the maximum displacement to the height of the slope

will be increasing rapidly at a certain time step. When ratio ?max / H is between 0.05 and 0.1

the reduction multiplier corresponding to the numerical non-convergence state or the ratio increasing rapidly moment is suggested to be the safety factor of the slope.
