Structural Stability Analysis of High Pile Wharf under Dynamic Load

摘要

A heavy equipment wharf intends to ship11100 tons "upper part of self-elevating offshore platform", the offshore platform located in the rear of the wharf base terminal yard, adjacent to the pile platform. The finite element software ABAQUS is used to analysis of the "upper part of structure" stress, deformation and stability of heavy equipment wharf when shipped from terminal yard to the sea. Results showed that only under its own gravity and pile wharf, pile cap, slide stress are much lower than the design strength of the material and the displacement were not more than 1mm, but in sliding area, different types of cap expansion joints and near cloud rail are stress concentration degree is serious, force has exceeded the material yield strength. The results of calculation for modify the plan of the shipment platform and provide reference data of transportation security, and put forward the corresponding suggestions.
