用石灰处理高含水填土

本文分析了石灰对土的压缩性、强度及塑性等工程性质的影响、叙述了用石灰处理高含水填土的作用机理,结合实际工程介绍了石灰处理高含水填土的施工方法及注意事项.试验结果表明:石灰处理后土的最优含水量增大,最大干容重减小,强度明显增大,塑性降低,便于压实并可达到较高的强度.试验路基的测试结果表明:采用适当的施工方法,使用石灰处理高含水填土能起到缩短工期、降低造价和提高质量的效果.

Mud Compacted Fill Stabilization with Lime

In the construction of earth dams and embankments, a large amount of fill needs to be compacted. The water content of fill is often higher that the optimum water content when construction is in rainy seanon and construction site is in wet spot where ground water level is high. Lime can be used to dry up mud, siabilize soil and prevent delay of construction. The compactability, strength, plasticity and other engineering behaviors of soils stabilized with lime have been studied in this paper and the mechanism of mud opmpacted fill stabilized with lime hays been presented. Concerning actual engineering, construction method and some other detaited problems have been discussed too.
