Improvement of Peck Formula in Subway Construction in Beijing

Yao Aijun,Zhao Qiang,Guan Jiang,Liu Fangyuan,Su Ning (The Key Laboratory of Urban Security and Disaster Engineering of Ministry of Education Beijing University of Technology,Beijing 100124,China)  
Because of many influential factors during subway tunnel construction,some common prediction methods of surface subsidence have limitations,and the prediction results have large gap in practical engineering.Therefore,this paper develops an improved Peck formula by introducing two correction factors: the maximum surface subsidence correction coefficient α,the width of settlement trough correction factor β.Through a large number of measured data of regression analysis,it is found that when α is between 0.6 ~ 0.9,and β is between 0.5 ~ 0.9,the curves can give a good prediction.
