斜坡地基极限承载力下限解计算

为了研究斜坡地基的破坏机理，基于极限平衡法理论，建立了一个新的能考虑坡后土体坡度影响的斜坡地基承载力的计算模式，通过FORTRAN语言编制了斜坡地基坡后土体的发挥系数的计算程序，分析了斜坡地基内摩擦角、基础下侧土体坡度、基础上侧土体坡度、相对坡顶距及基础相对埋深等因素对斜坡地基极限承载力性能的影响，得出了不同地基情况下斜坡地基坡后土体的发挥系数。得到的斜坡地基的承载力系数和发挥系数可用于斜坡地基的理论分析和设计中。

Calculation of low limit solution of sloping ground ultimate load capacity

Based on the theory of limit equilibrium,a new calculation module was presented to study the fracture mechanism of sloping ground,which could consider the effect of ascent of fill section at the back of slopes.To gain the mobilization factor of the fill section at the back of the sloping ground, the program was written with FORTRAN.In the calculation of the ultimate load capacity of sloping ground,the effects were considered,which included angle of internal friction of the sloping ground,underside slope angle,upside slope angle,relative distance from the edge of slopes and relative depth of footings.The mobilization factor of the fill section at the back of the sloping ground in different conditions was gained.Meanwhile,the load capacity factors and mobilization factor could be used in theory analysis and design of sloping ground.
