Abstract
Landslide disasters constitute one of the primary natural disasters in human history. Understanding calculation methods for landslide residual sliding force enables the targeted design of landslide treatment schemes. Given the current scarcity of research and engineering practice on wedge-shaped landslides, this paper proposes a calculation method for the residual sliding force of wedge-shaped landslides and verifies its rationality through engineering case studies. The results demonstrate that, compared with residual sliding force calculation values in existing anti-slide pile designs, the values obtained by the proposed method differ by 12.9%. This innovative method provides key technical support for landslide engineering projects, effectively reduces landslide disaster risks, and safeguards people's lives, property, and ecological environment security.

Abstract
Landslide disasters rank among the most significant natural hazards in human history, making the understanding of residual sliding force calculation methods essential for designing targeted remediation schemes. However, research and engineering practice focused on wedge-shaped landslides remain relatively limited. This study addresses this gap by proposing a novel calculation method for determining the residual sliding force of wedge-shaped landslides and demonstrating its validity through practical engineering applications. The results reveal that values obtained using the proposed method differ by 12.9% from those calculated through conventional anti-slide pile design approaches. This innovative methodology provides critical technical support for landslide engineering projects, effectively mitigating disaster risks while safeguarding lives, property, and environmental security.
