摘要
土基回弹模量是路面结构设计中必不可少的设计参数,它直接影响路面的设计厚度。通过采用现场承载板法对沿江地区吹填砂路基土回弹模量进行试验研究,结果表明,吹填砂路基土经过处理后,土基回弹模量得到了很大提高,为制定路基土回弹模量的测试方法和取值标准提供参考。
Resilient module of soil foundation is the essential parameter in pavement structure design, which directly influences design thickness of pavement. This paper carries out experimental research on resilience modulus of foundation soil with hydraulic fill sand along river with loading plate on the site. It is indicated from result that the resilience modulus of soil foundation with hydraulic fill sand is largely increased through treatment, which provides reference for establishment of test method and value standard of resilience modulus of foundation soil.
