摘要
Abstract
The blasting construction of newly constructed tunnel inevitably influences the existing tunnel's safety.Based on the extension project of Houci tunnel in Xiarong highway of Fujian Province,the influence law of the newly constructed tunnel blasting vibration on the existing tunnel is studied.Combined field monitoring with numerical simulation,the dynamic response characteristics of the cross-section and axis direction of the existing tunnel is obtained,which is pointed out to be influenced obviously by multiple external factors (surrounding rock type,the thickness of mid-adjacent rock,the excavation size,free-surface condition).关键词
