Research on Protection Design of Tunnel Micropile-Anchor Rope on Slope under European Standard
At present,there is little research on the protection types of tunnel slope in European standard,especially for micro-pile-anchor cable on slope protection.Based on E60 high speed TUN2009 tunnel in Georgia,the de-sign and deformation and stress analysis in European standard with micro-pile anchor cable on slope protec-tion are carried out,and the design and calculation method of micro-pile anchor cable on slope protection are obtained.At the same time,numerical simulation method and field measurement are used to analyze the defor-mation and stress characteristics of the slope in European standard by using micropile anchor rope slope pro-tection.The results show that the deformation and bearing capacity of micropile,the bearing capacity of the anchor cable and connecting steel frame and the overall stability of the slope meet the requirements.
