Abstract: The anti-slide casino is one of the commonly used measures for slope stabilization. Owing to its advanced theory and well-developed construction plans, it is extensively applied in the mitigation of high and steep slopes and landslides across various sectors, including transportation, water conservancy, construction, railway, municipal engineering, and geological hazard mitigation in practical engineering applications. This article presents the slope stabilization project associated with the relocation of the First Middle School in Dafang County, Guizhou Province. The geological conditions and a comparative analysis of the functions of three support design options: anti-slide square caissons, prestressed anchored anti-slide square caissons, and prestressed anchored anti-slide circular caissons are introduced with focusing on the lateral capacity. The paper further discusses the economic advantages and disadvantages of these three options within the transportation industry's standards. Lastly, the article examines the differences between theoretical design and practical application, along with the potential uncertainties in the application. The comprehensive and systematic overview of the design process for anti-slide caissons offers significant reference value to related engineering projects.
