Abstract

With the rapid development of infrastructure in China, the number of slopes created by excavations for roads, tunnels, and other engineering projects has been steadily increasing, accompanied by a rise in natural hazards induced by slope instability. Owing to the complex engineering geological conditions, slopes often require appropriate support measures after excavation to ensure operational stability. The strata typically comprise mudstone, sandstone, shale, or a combination thereof. The presence of soft rock significantly reduces the mechanical strength of the slope, rendering soft-rock slopes less stable compared to those composed of hard rock. Consequently, assessing the effectiveness of slope support measures is of critical importance. This paper presents a comprehensive review of domestic and international research on slope stabilization techniques, including prestressed anchor frameworks and anti-slide piles. The interactions between support structures and the surrounding geotechnical body are analyzed to provide a theoretical foundation for the design and optimization of future slope support measures.
