Abstract

Landslide disasters are one of the major natural hazards in human history. Understanding the calculation method for the residual sliding force of landslides can enable targeted design of landslide control measures. Given the relatively limited research and engineering practice concerning wedge-shaped landslides, this paper proposes a calculation method for the residual sliding force of wedge-shaped landslides and validates the rationality of this method through engineering case studies. The results show that the calculated values obtained by the proposed method differ by 12.9% compared to the residual sliding force values used in existing anti-slide pile designs. This innovative method provides crucial technical support for landslide engineering construction, effectively reducing landslide disaster risks and safeguarding public life, property, and ecological environment security.
