Estimating the Effects of Tunnelling on Preexisting Jointed Pipelines

Figure 6

Influence of the distance between a joint and the locus of maximum ground settlement on a jointed pipeline. (a) Influence of the distance between a joint and the locus of maximum ground settlement on maximum joint rotation. (b) Influence of the distance between a joint and the locus of maximum ground settlement on maximum pipe bending strain. (c) Influence of the distance between a joint and the locus of maximum ground settlement on maximum vertical displacement.
