摘要：

This paper deals with the numerical aspects of an extensive research programme aimed at the study of interaction phenomena occurring between a pipeline and the surrounding soil when the pipeline crosses slowly deforming slopes. A numerical analysis of the soil-pipe interaction problem is performed using a finite element discretisation of the pipe and a non linear spring-type model for representing soil response. The geometry of the problem is treated as fully 3D and the interaction forces arising at the soil pipe interface are set to satisfy the pipe-soil interaction patterns as obtained from past research work involving field and laboratory testing. By imposing a slope deformation field as boundary condition, the model gives the stress distribution in the pipe as it results from the complete solution of the soil-pipe interaction problem. The stress distributions obtained through the model are compared with those inferred by monitoring strains along the pipe.
