铁路粉土路基土的变形与强度特性试验研究

Test Study on Deformation and Strength Behaviors of Compacted Silt Soil of Railroad Subgrade

为研究粉土铁路路基的稳定性,在室内进行了不同密实度和含水率压实粉土的三轴剪切试验,并得到了路基粉土的变形与强度性质随压实系数和含水率的变化规律,为分析和评价粉土铁路路基的稳定性提供了大量充实的试验数据。

In order to evaluate and treat the silt subgrade diseases caused by rainfall of Beijing-Jiulong railway in the Yellow-River alluvial plain area, an indoor three-axis shear experiment on compacted silt soil of different densities and moisture content has been carried out. The rule that the deformation and strength of subgrade＇ s silt change with the coefficient of consolidation and the moisture content is generalized, which will provide ample experimental data for analyzing and evaluating the stability of silt soil railroad subgrade.
