Abstract

Abstract: There are more shield tunnellings near the pile of the bridge in the downtown, the problem of the effects of shield tunnelling on the nearby piles of the bridge need to be studied. The numerical analysis method is used to study this problem. And than a numerical analysis model is established. The settlement of the pile, the lateral displacement of the pile and the settlement of the ground induced by the shield tunneling are analyzed. The settlement of the pile, the lateral displacement of the pile, the settlement of the ground during the shield tunnelling and after the tunnel crossing the pile is in controllable. The results of the numerical analysis and the results of monitoring are compared; and the results are similar to each other, so as to show the reliable of using the numerical analysis method to study the effects of the shield tunnelling on the nearby piles.

Key words: shield tunnelling, numerical analysis, field monitoring, nearby piles
