Abstract: The buried pipelines, such as water, gas and heat supply pipelines, are widely distributed in urban areas. The seismic responses of pipeline are significant affected by the spatial variability of soil properties along the pipeline. In this paper, the multi-variable random field method was used to generate random soil properties along the pipeline and the elastic foundation beam model was used for seismic response analysis of pipeline under passage wave. The influence of critical soil parameter correlations on joint deformations and pipe strain was investigated for the pipelines with rigid joint and flexible joint. The numerical results show that the joint openings are significantly affected by the stiffness differences of soil springs connected to the adjacent pipes. The decrease of spatial correlation of soil parameters leads to the increase of stiffness differences of the soil springs along the pipelines, which increase the variability of joint openings along the pipelines. The pipe joint responses obtained from the model considering spatial correlation of soil properties are 7.9%~27.9% higher than the deterministic model. The flexible joint is more susceptible to the randomness of soil parameters along the pipeline.
