路基压实变形模量检测标准分析

Detection Standard of Deformation Modulus in Subgrade Compacting

通过介绍法、德两国路基变形模量检测试验以及铁路、公路的变形模量标准和应用情况,分析认为:变形模量是力学指标,能反映路基的压实质量和受力性能;变形模量标准与压实条件和填料有密切关系,应经过大量试验研究来制定。建议我国公路进行研究或参照高铁做法引入采用。

By introducing the detection tests of subgrade deformation modulus, the deformation modulus standards of railway and highway as well as their application situation in France and Germany, it is believed that：deformation modulus is a mechanics index which can reflect the compacting quality and bearing performance of subgrade; the standard of deformation modulus is closely related to compacting condition and filling materials, which should be instituted based on numerous experimental studies. It is suggested that studying the standard of highway in China or introducing and applying the operation in high-speed railway.
