摘要： 当斜坡存在时，地基与基桩承载力的计算方法与平地条件表现出差异性。已有很多学者分析、研究了斜坡条件地基与基桩承载力的确定方法，利用MATLAB进行斜坡条件承载力计算程序的开发，将斜坡条件下地基与基桩承载力计算方法集成在程序中。结合算例，结果说明该程序在文献基础上利用调整系数法插值计算斜坡条件地基与基桩承载力的结果是准确的，并分析了斜坡坡比对承载力的影响：承载力与坡比呈负相关关系，随着斜坡坡比的减小，承载力有增加的趋势，但增加的程度与坡比有关。

Abstract: Under sloped conditions, the methods of calculating the foundation and pile bearing capacity are different from the those in leveled ground and various methods from different researches for the determining the foundation and pile bearing capacity under sloped conditions are proposed.A new analytical approach for the soil bearing capacity and pile axial capacity under the sloped condition is proposed by using MATLAB software. Combined with numerical examples,the results illustrate the proposed calculation method in the program by using the interpolation method with the adjustment coefficients are relatively accurate and comparable with the historical data.The influence of the slope ratio on the bearing capacity is also presented: the bearing capacity and slope ratio was inversely correlated,with the slope ratio decreases,the capacity increases, and the degree of capacity increase is related to the slope ratio.
