CPT-based design method for steel pipe piles driven in very dense silica sands compared to the Euripides pile load test results

摘要

A CPT design method, based on a modification of the original UWA and IC-MTD methods, is compared to the results of the large-scale Euripides pile load tests, representative of the very dense silica sands of the southern North Sea area. The comparison with the currently applied API RP 2 A design model shows that the recommended criterion with a maximum limiting friction resistance is the main cause for the conservative bearing capacities calculated in very dense silica sands. The application of the proposed design method is illustrated with a case history from the Dutch sector of the North Sea.
