| 摘 要： | 膨胀土的强烈亲水性使得其用于路堤填料时要兼顾强度与水稳性的要求,在根据现行规范《公路路基设计规范》(JTJ013-95)用一个压实度指标的基础上,同时考虑饱和度作为压实时的另一控制指标,用这两项指标共同实现路堤压实稳定。这种压实控制方法用于成都市三环路工程中,取得了较好的效果。

| Abstract: | Its intensity and water-stability have to be taken into account for expansive clay embankment given the characteristics of the expansive clay. Based on single compactness index under the current standards (JTJ013-95) in China, saturation degree should be served as an other compaction control index so as to make the compacted embankment more stable.The compaction control method is applied in the third-ring road in Chengdu with better result. |
