Abstract:Research purposes: There are serious geological disasters in the area where the Mengzi-hekou Railway passes through. Based on the deciphering with remote sensing, site surveying, integrative exploration, and active fracture identifying and so on, the analyses of distribution and cause for regional geological disasters are made, the principles of geological mute selection is presented and the scheme with better geological conditions is recommended for the purposes of making the construction feasible in technology and reasonable in economy.
Research results: The distribution of geological disasters along Mengzi-Hekou Railway presents obviously territorial; the division of east and west area is Longgutang-Jimi-Nanhan Great Fracture, which is made by landform, climate, areal geological structure and new tectogenesis, stratum and lithology, and human work and so on. Based on the research of geological disaster in this area, the mid-line scheme with preponderant geological condition is adopted, which reduces the difficulty in construction and hidden troubles followed, and increases the mute scheme's feasibility and reliability.
