Abstract:

Soil differential-settlement， which will change the stress state of buried pipelines， is one of the important causes for the damage of the buried pipelines. In this paper， pipeline-soil integrated models are established for four kinds of pipelines by utilizing the ABAQUS software. For continuous pipelines， such as steel pipelines and PE pipelines， the stress response of the pipelines are mainly analyzed. But for socket pipelines， represented by ductile iron pipelines and grey cast iron pipelines， the joint deformation is the mainly research object. Thus， the soil settlement displacement that causes the limit state of pipelines are obtained， which reflects the anti-settlement ability of different types of pipelines. Moreover， the effects of pipe diameter and length of the soil settlement area are discussed.

Key words:soil differential-settlement;steel pipeline;PE pipeline;ductile iron pipeline;grey cast iron pipeline;ultimate soil settlement displacement
