摘要
影响高切坡稳定性的因素复杂多样,边坡上荷载的加载方式与边坡的几何形状是诱发高切坡失稳的两个主要因素。基于ABAQUS软件,运用有限元强度折减法,研究了高切坡的坡顶和坡脚在矩形均布荷载作用下,其几何形状与荷载变化时高切坡的稳定性及潜在滑动面位置的变化规律。研究表明:高切坡的稳定性随坡角和荷载的增大均先增大后减小;潜在滑动面随坡角增大不断下降并有逐渐通过坡趾的趋势。
There are many complex factors that affect the stability of slopes, however the way of loading on the slope and the geometry of slope is the two main factors which lead to the slope instability. Based on ABAQUS software, and using shear strength reduction finite element method, we study the var- iation law of the stability and the location of potential slip surface of high cut slopes under rectangle uni- form load, with the change of the loading way on the slope. The research results indicate that its stability first increased and then decreased with the increase of the slope angle and the loading on the slope; po- tential sling surface has the tendency of gradually through the slope toe with increase of the slope angle.
