The Failure Mechanism Analysis and Control of the Underground Pipelines During Rectangular Pipe Jacking Construction

Because pipe jacking inevitably results in disturbances of the surrounding soil, causing ground movement, thereby threatening the safety of nearby underground pipeline. Based on the rectangular pipe jacking con-struction of a subway station export municipal channel, the interaction between underground pipelines and soil is analyzed; the distributions of stresses and displacements of the pipeline are discussed; its failure mechanism is sum-marized, and the corresponding control measures are described.
