1. Slope Stabilization of GuanYin Railway Station in China XiaoLiang Wu Yu DI

2. Properties of granite Introduction Geological Condition Problems 1 1 2 2 3 3 4 4 Contents 5 5 Solutions

3. Introduction GuanYin railway station located at the right side of a rock slope which is 60m~80m higher than the railway ballast Landslides are a primary hazard to railway Tectogenesis and the exploding technology lead to cracks in the rocks

4. Geological Condition Granite is the main component of the rock The natural slope and eroded by river

6. Granite Granite is an igneous rock As old as the earth The physical and chemical properties

7. Problems Vertical Cracks → Instability of the slope Causes of cracks →Several times tectogenesis performed many joints in the vertical direction →Using of exploding technology made the crack bacame bigger →Rain falls in the summer and the increas of the water volume

8. Solutions Cast concrete in the cracks → Increase the interaction of rocks → Increase the strength of rocks Reinforced nails → Provide tension force → Increase the integrality of the whole slope → Resist the slide of slope
