Relation between Jacking Force and Jacking Path in Pipe-packing Construction and Analysis on the Influence Factors

Abstract:

In the construction of a long distance pipe-jacking tunnel with small curvature in Shanghai, jacking forces of four pipes in jacking path are measured. Based on the on- site observation,this article studies the changing pattern of jacking force in different jacking path and analyses the main influence factors to jacking force in construction, some useful conclusions are obtained.
