【 摘 要 】

Wangqiao tunnel of Jiu-jing-qu railway is used as engineering example, based on risk analysis, aim at the construction scheme, comprehensive analysis and calculation has carried on combined monitoring and numerical analysis. Reliability demonstration has conducted on comprehensive construction scheme of" ground surface grunting consolidation & mechanical excavation & improving support measure & settlement monitoring". Practice has proved that the deformation of the tunnel's settlement of the arch and the high-voltage transmission tower were in allowable ranges, and good economic and technical results are obtained, the results can provide a reference for similar projects.
