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 triaxial test results of two different kinds of non-woven ribs reinforced sand have shown that the strength indexes c and values of the non-woven reinforced sand are significantly increased, and the reinforced soil strength is related to the sleep pressure and regularity of the reinforced specimen. The increase in h/H of the reinforced ribs increases and the interaction between the nonwoven ribs and the sand can inhibit the dilatancy of the sand, and the friction angle induced by the interface between the reinforcement and the sand is progressive. These research results have certain guiding significance for the study of the performance mechanism of reinforced sand and the design of reinforced soil structure.
