摘要
介绍了大粒径填料地基系数K30试验的试验方法。根据京沪高速、京石客运专线铁路路基施工现场不同直径的平板载荷试验数据,分析并提出了300 mm、400 mm、600 mm直径承载板试验的地基系数之间的换算关系。
This article introduces the test method of foundation coefficient K30 of large particle fillers. According to the plate loading experimental data of different diameters in the railway foundation construction sites of Beijing-Shanghai High Speed Railway and Beijing-Shijiazhuang Passenger Special Line, it analyzes and puts forward the conversion relationship of the foundation coefficients among supporting plates of 300 ram, 400 mm and 600 mm diameters.
