摘要
通过有限元软件利用强度折减法模拟计算土质边坡的安全系数,分析土体抗剪强度与边坡坡体安全系数之间的函数关系,土质边坡的安全系数与土体的粘聚力c之间呈线性相关关系;土质坡体的安全系数与土体的内摩擦角Φ之间呈二次多项式相关关系;安全系数与粘聚力c、内摩擦角Φ呈正相关性,且内摩擦角Φ对坡体安全系数的影响作用要大于粘聚力c对其的影响。
Using finite element software simulation to calculate the strength reduction factor of safety of the use of soil slope, this paper analyzes as a function of cohesion soil shear strength and slope safety factor , and the safety coefficient of soil slope is linearly dependent with the cohesion of soil ; quadratic polynomial correlation between internal friction angle of slope safety factor of soil and soil; safety factor and cohesion, internal friction angle was positively correlated, and the internal friction angle of slope the influence of the safety factor is greater than the impact of cohesion on it.
