第二讲斜楔法(续) (三)图解法边坡稳定分析的图解法包括用图解表示弱面的产状、两弱面组合交线方位与倾角及各组合交线间的夹角和用图解法分析滑体的受力。与上两法比较,图解法计算异常简便迅速,且几何意义与物理意义明确,不足的是计算精度较差。结构面及弱面及其组合交线的产状等可用吴尔弗(Wullf)网或兰伯特-斯密特网 Lecture 2 The wedge method (continued) (3) The graphic method of the graphical method for slope stability analysis includes the graphical representation of the occurrence of the weak surface, the combination of the azimuth and inclination of the combination of the two weak surfaces, and the angle between the intersecting lines of each combination. Graphically analyze the force of the slider. Compared with the previous two methods, the graphical method is very simple and rapid in calculation, and the geometric and physical meanings are clear. The lack of calculation accuracy is poor. The appearance of structural planes and weak planes and their combination lines can be used by Wulff or Lambert-Smittel.com
