Landslide Body Stability Analysis And Researched Of Synthesis Government In ShanXi Da-Xi Ditch Iron Mine

The ShanXi Da-Xi ditch iron mine is a key project in The Dragon Steel Group, which causes many mountains to slide in the construction process; especially the landslide in hole brings most influence. Because attention lacking and governable plan bring defeat after the landslide producing, the landslide threat directly to the security of area construction and inhabitant. Therefore, the research of landslide stability and the plan of landslide body government have important practical significance.Through Field geological investigation on the current of The Da-Xi ditch iron mine, the paper analyzed the elements include geology condition, hydrology condition, landslide characteristic, landslide cause. The result show that landslide produced on the interface of rock which belong to induct landslide type and ancient landslide resurrection. The paper applied the Coefficient Transfer Method to check the stability of landslide. In order to organize the stability of landslide program, the author made a program with Excel2003, which considered the accuracy of investigation work and the uncertainty of rock parameter in calculating. Calculating results show that the landslide body stability is dangerous on current condition, which will decrease gradually along with artificial engineering activity. The paper used the anti-play analysis to get the parameter(c,φvalue) of landslide belt in the Excel 2003. According to anti-play analysis result F_s-c,F_s-φrelation curve diagram that can obtain its accurate value. After the original landslide design losting, according to the landslide body stability analysis result, the synthesis considered each design target, the paper applied the synthesis preventable plan of govern hole landslide body with the board anchor combination retaining wall and pre-stressing anchor rope, which got the relational parameter and drawing of the hole landslide retaining structure by the calculation. After the landslide government working, the paper calculated the retaining structure anchor bar and shape guantity of anchor with Hooke Law. The examinated value of landslide government retaining structure is identical with calcutated value, it shows that the landslide body government plan is feasible.
