EXCAVATION ON ADJACENT BURIED PIPELINE INFLUENCE LAW RESEARCH

Recently, with the development of aspect on foundation pit excavation. the accident of pipelines deformation and pipelines fracture happened frequently due to foundation pit excavation. Now, this research subject is becoming more and more attention. Based on the finite element software ABAQUS, using the method of numerical simulation. In this paper, the influence of excavation on adjust buried pipeline are studied by author. Also in this paper, the author analysis the buried pipelines under the different pipe diameter and different material, studied on displacement of excavation of buried pipelines, the authors conclude and sum up the influence of different diameters and different materials on the displacement of the pipelines during the excavation.
