... conducted as well. To estimate the rigid spiral pile's ultimate lateral capacity in dense sandy soil, a simplified model is proposed based on Winkler's assumption by modifying an ultimate lateral soil resistance. INTRODUCTION In the state of the pile foundation's art, novel types of piles have been...

... ABSTRACT In this paper we analyzed the pipeline walking caused by thermal transient considering soil resistance variation within one loading cycle. Results show that the walking rate according to existing analytical solution could be larger or smaller than the actual walking rate, because...

Further, Been et al. (1990) and Croasdale et al. (2005) considered the soil deformation ahead of the berg keel, assuming two...

... resistance to the pipeline during the dynamic laying process is back-analyzed by a sophisticated method in which the reduction of the stress concentration with the increased embedment of the pipeline is well considered. The remolded soil resistance to the pipeline is found to be 0.48~0.74 of the intact soil...
