Abstract： Influence of ultra-high slopes on the existing tunnels and countermeasures are studied by an engineering example two-dimensional model with FLAC procedure combined with the experience of design and construction of slope engineering. This research mainly includes the distribution laws of stress and strain on tunnels of unbraced and braced ultra-high slopes and the countermeasure of retaining structures. It is of important theoretical and practical significance.
