Study On Stability And Design Administration Of The2nd Landslide In Liujiamiao

This paper focuses on a study of the2nd landslide of Liujia temple country on the left ofShuiluo river in Zhuanglang County of Pingliang City,summarizing meteorology, hydrology,topography,formation lithology, geological structure and seismic,hydrogeological and humanengineering activities of the landslide area. Based on this,through studying deeply the basiccharacteristics and the formation mechanism of the landslide and analyzing quantitatively thestability of the landslide,which propose governance research design,presently summarizes asfollows:High steep slopes and special formations (shale) is internal to generate the landslide; rainand earthquakes are the main external factors.(2) On the basis of qualitative analysis of the formation mechanism of the landslide we usefinite element numerical simulation software-Midas/GTS for Ⅰ profiles of the2nd landslide ofLiujia temple to establish Two-dimensional simulation. Then using strength reduction calculate itsstability and analyze the characteristics of displacement and stress-strain.The results shows that innormal conditions the landslide is basic stability and the possibility of bodily movements is less.In a non-normal conditionⅠ and Ⅱ,when displacement,stress and strain becomes large,thelandslide will be instability and may occur a whole slide threatening the balance of the proposedhighway embankment..(3)Using Transfer coefficient method in studying stability of the landslide in three differentconditions,we make the following conclusions:Under normal conditions,the stability factor of upper landslide is range from1.437to2.201,steady state; the stability factor of lower landslide is range from1.165to1.285,basicallystable; Under abnormal conditions Ⅰ,the stability factor of upper landslide is range from1347to2.06,steady state; the stability factor of lower landslide is range from1.093to1.203,less stable tostable; Under non-normal conditions Ⅱ,the stability factor of upper landslide is range from1.088to1.561,less stable; the stability factor of lower landslide is range from0.913to0.988,unstable，will slide again once loss steady; The stability results calculated in this paper can reflect the actualsituation of the landslide better and is consistent with the findings in the field survey.(4) By using entropy decision method to optimize the governance program of the landslide， comprehensive treatment Pragram is considered one of the most reasonable solution，namelygeneral anti-slide pile+integrated surface drainage+plant slope protection，Meanwhile，in paperthe anti-slide pile of the program designed.
