Numerical Simulation of the Influence of Row Piling on Underground Pipelines

Previous research on soil compaction effect mainly focused on single pile, and the analysis of the effect in the group piles was less. In the actual process, though, the design and construction of pile foundation engineering are based on the form of group piles. In order to further study the effect of construction of group piles on an underground pipeline, a three-dimensional entity model is adopted. The displacement penetration method is used to complete the process of piling. The friction between piles and soil, pipe and soil, large deformation and nonlinear factors are taken into account. The process of piling is more in line with the actual process. Taking the penetration of row piles for example, the numerical simulation of the static pressure pile is carried on under the condition of different piling sequences and the change of stress and displacement are analyzed. The results show that all kinds of stress and displacement of underground pipeline produced by the penetration of row piles increase cumulatively as the penetration of each pile and the stress and displacement of pipeline produced by the penetration of each pile are related with the sequence of piling.
