... SCR. The results of these programs were captured in a nonlinear soil-SCR interaction model described by Bridge et al. (2004). However, this model did not adequately describe the degradation in the soil stiffness resulting from the pipe separation from the soil. The effect of the pipe-soil separation...

... and geotechnical parameters. The results from these analyses agree fairly well with the measured behaviour of the platform. It is shown how an even better agreement can be obtained through tuning the structural stiffness and the soil stiffness. INTRODUCTION The Norwegian Geotechnical Institute (NGI...
