The lithologic characteristics and engineering geological characteristics of red sandstone were taken as the starting point. The special mineral composition, structure and weathering characteristic of red sandstone on the influence of slope instability were studied. On this basis, the relationship between different water content and red sandstone softening, disintegration characteristics was analyzed. The red sandstone bedding slope sliding failure mechanism in Chang-Ji highway was explained and the safety coefficient was calculated in the form of a numerical example. It is concluded that the ...
