一、特征曲线的基本理论工程建设中常用边坡稳定检算对填挖土坡或天然土坡进行评价,旨在确保建筑物的稳定安全,并且选择合理经济的工程方案,所以土坡稳定检算不但对工程质量、投资有关,且为节约用地、节约劳力的具体措施。如果检算方法不能切合实际,其结果既不安全,又不经济。为此,长期以来,对土坡稳定检算方法有所争论。目前应用的边坡稳定计算方法,主要分成二类:第一类是假定任何形状的滑动面(直线、圆弧、复杂的曲线
First, the basic theory of the characteristic curve Commonly used in the construction of slope stability check fill excavation slope or natural slope to evaluate, to ensure the stability and safety of buildings, and choose a reasonable and economical engineering solutions, so the stability of the soil slope Not only on the project quality, investment, and to save land, labor-saving concrete measures. If the test method can not be realistic, the result is neither safe nor economical. Therefore, for a long time, there has been controversy about the method of soil slope stability checking. The slope stability calculation methods currently used are mainly divided into two categories. The first type is the sliding surface assuming any shape (straight line, arc, complex curve
