Analysis of Settlement Caused by Tunnel Underneath Existing Railway after Construction

Abstract:

For the existing railway, the settlement after construction caused by the tunnel underneath it is completed after the tunnel has been constructed. It is the result that the stress adjustment and consolidation of soil enhanced itself under the live load of train. Through the settlement can be calculated by peck formula in the stage of and after construction, for the settlement after construction, the peck formula must be transformed with the fitting monitoring curve. With the engineering example, the fitting formula of settlement after construction can be used for analysis and prediction of similar engineering.
