Abstract
The engineering geological conditions in southwest mountain areas are complex, and landslide instability often occurs in the high-fill spoil ground of mountainous expressways, thus seriously hindering the expressway construction. By taking the high-fill spoil ground of an expressway in the southwest mountainous area as the research object, this paper employed data analysis and on-site survey to analyze the possible failure modes of the spoil ground. By combining the construction scheme and protective engineering design of the spoil ground, the safety of the spoil ground was qualitatively evaluated. Additionally, this paper conducted a comprehensive and systematic safety assessment of the stability, local and overall stability, and the stability of the retaining structure of the spoil ground by quantitative calculations, with the interception and drainage system verified. This can provide important analogical data and technical references for the stability assessment of high-fill spoil ground on other expressways.
