Research conclusions :(1)The talus compose of blocks and detritus and grain size is highly large. The porosity is very large and the gradation is poor. By gravity and groundwater, it takes on active tide and it is threaten to railway engineering. ( 2 ) Rock glacier side is steady that its lacunae is infilled by mass fine particle soil and frutex and arbor grows on it. By integrated survey, we made certain that surrounding rock quality of tunnels through rock pile zone is good and it is favorable to railway. ( 3 ) Via selection of technic and economy , the tunnel scheme is better than subgrade scheme and we select tunnel scheme finally.
