摘　　要：利用数理统计理论,通过对影响斜坡桥基承载力的各因素,包括桩径、桩长、桩身材料、岩体特性、桥基位置及斜坡坡度等进行回归分析,拟合出求解斜坡桥基承载力的一般表达式,对斜坡桥基的设计具有一定的指导意义。By utilization of mathematical statistics theory, the general expression of soluting the bearing capacity of slope bridge foundation is fitted out in the paper, through regression analysis of each influencing factor, including the pile diameter, pile length, pile material, rock mass property, bridge foundation position and gradient of slope, etc. The result has an important significance for guiding design of the high slope bridge foundations.
