摘要
通过对国内外标准进行研究,提出了承载板直径为40、60 cm的二次变形模量E_(v2)试验的试验方法。结合北京至上海高速铁路、北京至石家庄客运专线新建铁路路基施工现场的对比试验,对试验数据进行分析,得出承载板直径为30、40、60 cm的二次变形模量E_(v2)试验结果之间的相关关系,分析了填料最大粒径对试验结果的影响。
Through research on domestic and abroad standard, this article puts forward the test method of secondary modulus of deformation Ea on the loading plate, which is 30 cm, 40 cm in diameter. Based on the analysis of the experimental data of Beijing-Shanghai High Speed Railway and Beijing-Shijiazhuang Passenger Special Line, the related coefficient of secondary modulus of deformation Eaon the loading plate which is 30 cm, 40 cm and 60 cm in diameter is found out and the maximum size of particle of filler on the experiment is analyzed.
