摘要
As a typical mountain expressway, Jing-Cheng expressway (from Shayugou of Miyun to Beijing municipal boundary) is located in hilly area caused by tectonic denudation. Subjected to unique terrain restrictions, subgrade engineering digs deeply and fills high. And the expressway has lots of bridges and tunnels. So the problem of excavation slope stability is more pronounced. By using dynamic survey instruments, such as engineering geological mapping, exploration and field test survey instruments, RMR in rock mass classification and red even shoots the projection extremely, this paper evaluates the stability of the side slope and gives rationalization proposals of road construction and slope reinforcement program.
