【摘要】 边坡的稳定分析是岩土工程中的重要研究课题之一,在近百年的发展中,许多研究者致力于这一工作。因此,边坡稳定分析的内容十分丰富。极限平衡法作为传统而古老的方法,它在边坡稳定分析中是一种很重要的方法,一直以来在工程界被广泛应用。其主要原因是:它的概念清晰,很容易被工程人员理解和掌握:同时通过极限平衡法分析还能直接给出反映边坡稳定的安全系数的值。由于极限平衡法中的各种简化方法不同的假定条件,使得安全系数相差较大。针对安全系数的影响因素进行了详细的探讨。论文基于极限平衡理论,作了几点尝试性的改进:首先,假定滑面上应力分布形式,进一步将粘性土坡和无粘性土坡的滑面形式统一起来,在计算过程中不再根据粘聚力的大小来假定不同的滑面形式,均将滑动面形式假定为抛物线。其次,对圆弧的条分法和潜在滑动面搜索方法作了改进。再次,对岩质边坡倾倒破坏做了进一步的分析。更多还原

【Abstract】 The stability analysis of slopes is that one of important research problem in geotechnical engineering.About a centenary development, many pursuers are dedicating this work;Thus, the contents of the stability analysis of slopes are very abundant. The method of limit equilibrium is not only traditional.but also immemorial. It is a very important method in analysis of stabilization of slope.It is all through comprehensive application in engineering. The reason why is its vivid conception.It is very easy that understood and mastered by personnel of project;At the same time, it can direptly gives come into safety factors of stabilization of slope to make use of the method of limit equilibrium.Because different the predigest method of limit equilibrium, So as to safety factor is six to one for different suppositional conditions,this next carry through detailed discuss aim at affect diathesis of safety factor.This text is based upon limit equilibrium theoretics, it puts up attempt amelioration : Firstly , it is assumed stress distributing format of slip side,it is more unific for format of slope slip side about clay or not clay soil. In calculating process, format of slip side is not bases viscidity strength bulk,It is unific as parabola format. Secondly, the method of comminute piece of circularity arc and potential slip side cast are improved on.Furthermore,it is farther analysed for rock slope of rave about wreck.更多还原
