Instability Mechanism and Supporting Measure for Highway Tunnel with High Ground Stress and Soft Surrounding Rock
For the tunnel with high ground stress and soft surrounding rock, the deformation instability is the high frequency and great harm geological hazard. The supporting measure has become a important technique problem. This paper based on the Wuduxi tunnel, the characteristics of deformation and instability mechanism of surrounding rock and supporting structure are analyzed by means of the engineering geological investigation, theoretical analysis and field monitoring. The supporting measure include that using the steel floral tube to back up sidewall, adding support arch and filling foamed concrete, grouting reinforcement in basement. Finally, we use the field monitoring to check the supporting effect. The result shows that the supporting measure could achieve the desired treat effect and it has reference meaning to similar engineering.
