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
