Abstract

Abstract

Centrifugal model tests were conducted to investigate the influence of the reinforcement on soil settlement under confined conditions.Three tests were carried out.One has no reinforcement,the other two were reinforced with reinforcement(vertical)spacing of 5 cm and 3cm,respectively.The settlements of typical points ware recorded during the test.Results shows that settlements of the typical point increase with the increase of acceleration.The soil settlements without reinforcement,with 5cm spacing reinforcement and 3cm spacing reinforcement successively reduce,indicating that under confined conditions the reinforcement can still decrease the soil settlement.The smaller the reinforcement spacing,the better effect it can bring.The reason may likely lie in the facts that the soil displacement is uneven during the process of deformation.The study is helpful to understand comprehensively the mechanism of reinforced soil.
