摘要：
The marine pipelines or Steel Catenary Risers installed in deep offshore sediments are subject to significant cyclic loadings, mainly at the touch down point, where structural damage is often created. Because of this, it is important to study pipe-soil interaction in greater detail. This paper presents the results of experiments carried out using a half-scale model on an artificial soft soil, with emphasis on the influence of the different parameters on the horizontal pipe-soil stiffness. The parameters are the cyclic horizontal amplitude, the number of cycles and the weight of the pipe.
