| 摘 要： | 边坡稳定性分析的极限平衡理论中,仅考虑力的平衡的简化法(也称滑楔法)因其计算简便、快捷,广泛应用于国内外工程界.实践证明,对于圆孤滑面,滑楔法与严格条分法精度相当,但对于非圆孤滑面往往出现较大误差.根据对条间力倾角的不同假定情形,将滑楔法统分为第一类滑楔法和第二类滑楔法.建立了任意折线滑面边坡模型,以此分析滑体几何要素...

| Abstract: | Simplified limit equilibrium method for the slope stability analysis,which only consider the balance of forces(also known as sliding wedge method) has been widely used in domestic and international engineering for the simplicity and convenience in calculation.It has been proved that when the slip face is circle the accuracy of sliding wedge method is the same as that of rigorous method,but when the slip face is not circle sliding wedge method usually results in larger error.Based on the different assumption... |
