The invention discloses a simplified internal force calculation method for a straight-inclined combined pile foundation of a mountainous area slope, which adopts a reliable and simple stress calculation method for the straight-inclined combined pile foundation on the slope so as to save investment and work amount. Aiming at a bearing platform, a pile foundation, a landslide mass and bedrock on a side slope, factors such as basic bearing characteristics and a stress mode are fully considered, a complex three-dimensional geological problem is simplified into a plane strain problem, a simplified calculation analysis model of the straight-inclined combined pile foundation is established, a calculation formula of pile top deformation and pile body internal force is deduced, and support is provided for design and calculation of the internal force of the slope straight-inclined combined pile foundation. 本发明公开了一种山区斜坡直-斜组合桩基简化的内力计算方法，采用了可靠且简单易行的斜坡上直-斜组合桩基的受力计算方法，从而节约投资和工程量；本发明针对边坡上的承台、桩基、滑坡体及基岩，充分考虑其基本的承载特性和受力方式等因素，将复
