文摘At present the bored construction method is one of the main constructionmethods of metro and tunnel construction in China.The empirical estimated formuias oftunnel ground surface settlement using the bored construction method were obtained,combining the mechanical stimulant calculated result of tunnel model of different embed-ded depth,different cross section and different construction method and the actuai meas-urement data of Beijing metro construction.According to the regressed analysis of calcu-lated data,the calculated equations of ground surface settlement value and settlementrange of tunnel section under the condition of different embedded depth,different crosssection and different construction method were gained.Amongthem there are some em-pirical formulas can apply to the construction design of metro tunnel directly.
