Article Preview

Underground construction will inevitably disturb the surrounding rock and soil, thus endanger the safety of underground pipelines nearby. This paper has established the damage assessment of underground pipelines resulting from underground excavation. Based on GIS platform, it also has developed the damage assessment of underground pipelines and protection decision-making system. The extent of the excavation disturbance is determined through the prediction of the sinking value of the overlying soil caused by underground excavation. The stress and strain leading to deformation of the pipeline were analyzed using numerical simulation. The damage assessment for underground pipelines according to both macro and micro aspects was suggested to provide technical support during excavation of underground engineering disaster prevention and mitigation.
