Paper Title:
Effect of Shield Tunneling on the Nearby Pile Foundations
  Abstract

Shield tunneling may have negative influence on the nearby facilities. Especially, it will cause the additional stresses and moments along the pile shaft. If the stresses and deformation of a pile exceed the allowable values, that will affect its normal use and even result in its damage. Therefore, base on a practical engineering in Shanghai, some factors such as the distances between a pile and a tunnel, the concrete strength of a pile are investigated using finite diffrence method. The results show: the degree of disturbing soil in two sides of the tunnel is greater than that of soil in front of the tunnel; shield tunneling has a strong effect on a pile within a distance of 3m between the pile and the shield machine; however, if the distance is in excess of 3m, the effect is not too strong. Furthermore, the grade concrete strength of a pile has little effect on the pile behavior. This conclusion has some reference value to the actual project.
