边坡滑动体稳定性的评价,最终归结为稳定安全系 K 值的计算,K 是一个无因次数,数值为抗滑力矩与滑动力矩之比值,当 K>1时,边坡稳定;当 K=1时,边坡处于极限状态;当 K<1时,边坡处于不稳定状态。关于稳定安全系数 K 的计算方法,已有较多的研究,但目前工程上采用条分法计算,这是近似的数值计算法,精确合理的数解法正在发展。为此,本文提出均质直线边坡滑动体稳定性的数解计算式及进行边坡滑动的稳定分析。
The evaluation of the stability of the sliding body of the slope ultimately comes down to the calculation of the K value of the stable safety system. K is a factorless number and the value is the ratio of the anti-sliding torque to the sliding torque. When K>1, the slope is stable; when K When =1, the slope is in the limit state; when K<1, the slope is in an unstable state. There have been many studies on the calculation method for stabilizing the safety factor K. However, at present, the score method is used for engineering calculations. This is an approximate numerical calculation method. An accurate and reasonable number solution method is being developed. For this reason, this paper presents a numerical solution for the stability of the sliding body of a homogeneous linear slope and the stability analysis of slope sliding.
