| Abstract | 1、通过静力、动力试验，粉煤灰可用做路堤填料，改良后可用做路基基床填料；
2、粉煤灰有良好的工程特性，在含水量、压实、本体沉降等方面优于普通土；
3、粉煤灰包坡后不会对水质和周围环境造成污染；
4、粉煤灰自重轻，在地基处理和基底总沉降方面明显优与普通土，同时，利用粉煤灰填筑路堤，实现废物利用，节约用地，减少粉煤灰的扬灰污染，具有良好的工程和经济意义。 |
| Other Abstract | 1. Fly-ash can be used as road embankment filler according to some static and dynamic experiments, and the improved fly-ash can be used as roadbed filler;
2. Fly-ash has favorable engineering properties and is much better than ordinary soil in its water content, compaction, self-subsidence etc.
3.Fly-ash packed with soil won’t cause pollution to water or the surrounding environment.
4. Fly-ash is low in weight and therefore superior to ordinary soil in ground processing and gross roadbed (beneath the fly-ash layer) subsidence. Meanwhile, fly-ash used as roadbed filler has favorable engineering and economical significance in waste recycling, optimal land utilization and the reduction of ash emission. |
