摘要
提出了承载板直径分别为400,600 mm的二次变形模量EV2的试验方法,通过对京沪高速、京石客运专线铁路路基施工现场试验数据的分析,得出承载板直径分别为300,400,600 mm的二次变形模量EV2试验结果之间的相关关系,并分析了填料最大粒径对试验结果的影响。
This paper introduces the method of secondary deformation modulus Ev2 tests with the bearing plate relationship between test results of secondary deformation modulus En tests with the bearing plate having 300 mm, 400 mm and 600 mm in diameter respectively is obtained, at the same time, the effect of maximum filling material size on these test results is discussed.
