| 摘 要： | 筋土界面作用特性直接影响着土工结构物的强度和稳定性。在总结国内5种筋土界面作用特性观点的基础上,认为加筋土的强度和稳定性主要依靠填土自重和筋土之间的摩阻力来实现,加筋作用不仅反映在筋土界面上,也发生在筋土周围的土体中,加筋土的剪切带观点是对筋土界面特性的综合性概括。加筋填土的含水率、压实度、剪胀效应、加筋材料自身特性以及试验方法等因素都不同程度地影响着筋土界面作用特性。将直剪试验和拉拔试验相结合,并辅助离心模型试验及数值分析方法,可深入研究筋土界面作用特性。

| Abstract: | By means of analyzing 5 view points of interaction characteristics,it has been proved that strength and stability of reinforced soil mostly depend on weight of filling soil and the friction between reinforced material and soil.The reinforcing effect not only reflects on the interface but also occurs in the surrounding soil.It has concluded that view point of shearing strip is the comprehensive analysis on interaction characteristics.The water content,compaction,dilatancy,the characteristic of reinforced mat... |
