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

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

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

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

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
