摘要
两种不同的无纺布筋片加筋砂土三轴试验研究结果表明，无纺布加筋砂土强度指标c、值显著提高，加筋土强度随加筋试样所受困压和正规化加筋筋片间距h/H减小而增加，无纺布筋片与砂土之间的相互作用可抑制砂土剪胀性，筋砂界面诱生摩擦角呈渐进性。这些研究结果对加筋砂土的性能机理研究及加筋土结构设计均有一定的指导意义。
The result of study on the behavior of sand with two kinds of geotextile reinforcements showsthat the strength parameters C and 9 are more greatly enhanced than that of unedofored sand.The strength of reinforced sand increasies with enhancing confinillg pressure and decreaSingnormalized spacing (h/H) between reinforcement discs. Geotextile inclusion restrains the dilationof sand due to the interaction between sand and reinforcement and the mobilized internal frictionangle is progressive during shearing. These properties are significant tO the design Of reinforcedstructures as well as to the study of reinforcing mechanisms.
