Abstract Abstract:Research purposes: There is no systematic research on the damage mechanism of high loess slope which is influenced by the snow melt water,freezing coupling mechanism and long - term repetitive heavy train load. The disease mechanism,present situation and development trend of Longgong station ’ s high and steep slope are analyzed and a reasonable treatment scheme for high slope is discussed in this paper. Research conclusions :( 1) There should be a certain forward - looking for the railway station ’ s design,appropriate to consider the extension of the reserve expansion project or the extension of the line conditions. ( 2 ) Existing slope disease may be caused by many unfavorable factors instead of one unfavorable factor. ( 3 ) A safe and reliable design scheme of service operation should be developed according to the development trend of the existing railways diseases. (4) Under the influence of loess collapsibility,snow melt water, freezing coupling mechanism and long - term repetitive heavy train load,high loess slope easily become disaster point for operation of railway. (5)This research has certain reference for tlie treatment of high steep slope disease of heavy haul railway.
