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。
The test method of the K30 test on the coefficient of foundation of large particle size filler is introduced. According to the test data of flat-plate load with different diameters on the railway subgrade construction of Beijing-Shanghai Expressway and Beijing-Shijiazhuang Passenger Dedicated Railway, the relationship between the ground-based coefficients of 300 mm, 400 mm and 600 mm diameter bearing plate test is analyzed and proposed.
