Study On Development Law Of Geological Hazards Along Qinghai-Xizang Railway (Germu-Kunlun Pass)

Qinghai-Tibet Railway is located in the hinterland of qinghai-tibet plateau, thestarting point in the provincial capital xining of qinghai province, Tibet autonomousregion’s capital, Lhasa. Golmud to Lhasa, qinghai-tibet railway section from golmudin qinghai province, along the red table, wudaoliang, tuotuo river on mount tunggula,wild goose Shi Ping, via anduo, naqu, Tibet autonomous region male, yambajan,capital, Lhasa, Tibet autonomous region (1142km). But for a long time,hydrogeological environment geology investigation along qinghai-tibet railway isstagnant, and the region characteristic of hydrogeology and environmental geologyconditions, the plateau uplift and neotectonic movement mechanism, glacier retreatand change of water environment, lakes, marshes, atrophy, frozen soil disasters,desertification, and so on environmental geological problems related to thegroundwater resource is still not known to know, it is not only influence thedevelopment of the economy, sometimes will bring huge losses.Taking along qinghai-tibet railway as study area, the geological disasters in thearea as the main research object, through collecting zone existing geology, hydrology,hydrogeology and engineering geology in geotechnical engineering and geologicaldisasters, on the basis of the field investigation, verification is complementary,comprehensive analysis and study method, the combination of geological hazardalong qinghai-tibet railway for the comprehensive analysis and summary, thefollowing conclusions:(1)By investigating the landform, stratum lithology along qinghai-tibet railway,the height, regional structure and development characteristics, together with existingdata in this area, we believe that certain radioactive-polluted area in landscape on thelarge area can be divided into the qaidam basin area, east kunlun mountains area, theYangtze river headwaters residual high mountain plains and mount tunggula area andso on four big area.(2)By investigating in stratigraphic lithology, rock mass engineering geologicalproperties of rock and soil types in geotechnical engineering in the two major types,comprehensive investigation of the various factors influencing the engineeringgeological conditions in the area, can be divided into in permafrost regions and thepermafrost regions. Two big engineering geological area. The permafrost regions can be divided into the golmud strong falling piedmont diluvial sector of the ice water,kunlun river rising strongly plait broken high mountains, small sichuan monoclinalstructure high mountains, west beach down four rift valley area and the area; Inpermafrost regions can be divided into the fold of kunlun mountains rise stronglybroken high mountains, qumar downfaulted basin area, wind volcano slowly rising,tuotuo river on downfaulted basin area in middle and high mountain areas, happyridge mountains, wild goose in the slowly rising plait broken Shi Ping tang, gurastrongly up plait broken mountains and strong down downfaulted basin area and so onsix areas.(3)Through the investigation of geological hazard along qinghai-tibet railway,and developmental characteristics, combined with object, golmud-kunlun mountainsalong the internal force of main geological disasters as earthquake; External force ofgeological disasters are mainly wind erosion and sand buried collapse, debris flow,frost heave and subsidence, etc., of which the external force (frost heave subsidenceand landslide disasters.(4) Through the analysis of geological hazards and hazard object, combiningwith the field, for different disaster different prevention measures and engineeringmeasures are put forward.
