Pullout Resistance of Mechanically Stabilized Earth Wall Steel Strip Reinforcement in Uniform Aggregate, Technical Summary.

摘要

Eighteen pullout tests were carried out on ribbed steel strip reinforcements embedded in six aggregate backfills with uniformity coefficients ranging from 1.4 to 14. The pullout resistance of each reinforcement-backfill combination was investigated under three normal stresses to simulate reinforcements placed at different depths of fill. Each test sample was prepared in a consistent way to minimize variations. One of the important influence factors was degree of compaction.
