摘要
针对四种路基土质,在不同压实度条件下,利用PFWD测定各土样的动回弹模量E0,同时,通过室内试验测定各土样的CBR值,分析了E0与CBR随压实度变化规律,建立了浸水前后各土质E0与CBR相关关系式,研究成果为工程建设实践提供参考。
Considering of four kinds of subgrade soil, dynamic resilience modulus E0 of every soil are tested by PF- WD in different compactness. And CBR of every soil are tested by laboratory experiment at the same time. The variation law of Eo and CBR following with compactness are analyzed. Correlativity formulae between Eo and CBR of every soil before and after soaking are proposed. The study conducted in this paper provides reference for construction.
