Study on Mechanical Behaviors of Underground Pipelines Due to Excavation of Foundation Pit
It is necessary to study the mechanic behavior of underground pipelines during the excavation of the foundation pit, because the excavation will inevitably endanger the nearby underground pipelines. Three factors include the depth of underground pipelines, the distance from the pipeline to the foundation pit and ground load are considered to conform comparative analysis, in order to study the variaty on the stress and deformation of the underground pipelines. The foundation surporting type and the soil layer distribution are also considered during the numerical simulation. The results show that the distance between pipeline and foundation has more influence on the underground pipelines than other two factors, the damage most likely occurred in the bottom right in the pipeline near the foundation pit.
