| 摘 要： | 结合黄土的特性,选择预建高速公路的典型黄土,通过室内试验方法确定黄土的物理指标。通过黄土击实试验确定了该试样的最佳含水量为14.3%,与之相应的最大干密度为1.918 g/cm3。最后选择冲击式压路机在试压路段进行碾压,通过试验数据可知,在冲击压实达到40遍时,地面层20 cm的黄土的压实度能达到97.8%,黄土地基的总沉降量达到25.12 cm,且沉降趋于稳定。

| Abstract: | Combined with loess characteristics, the paper introduced how to select typical loess of pre-buih highway, determine the physical indexes of loess through indoor test methods.Finally, chosed impact roller to roll in the test road. The experiment data showed that the settlement was stable. |
