Exploratory study on the hooking of pipelines by excavating machines (EPRG report)

摘要

THE INTERACTION between a hydraulic excavator and a buried pipeline is considered in this study. A simplified mechanical model was established in order to estimate the force needed to pull the pipeline out of the ground as well as the mass of the excavator capable of exerting this force. The sensitivity of the results to the main parameters was studied on a set of pipelines representative of gas transmission.
