浅析焖灰在过湿土路基中的作用

过湿土天然含水量大,粘性大,其亲水性、持水性、透水性差,晾晒困难,施工难度大.原有处理过湿土的方法,如采用取土坑开沟排水,降低地下水位等存在施工周期长、受天气、场地因素影响大的缺点,利用生石灰焖灰处理可以有效克服上述缺点,文章详细介绍焖灰处理的工艺及对土质影响过程,并将此工序与老方法进行了比较,得出焖灰在公路施工中作用重大的结论.

On Braised Spodosol's Functions in Constructing on Overwet Soil Road Foundation

saturated soil is very adhesive and hard to dry with poor hydriphility and hydranlic permeability. So it is difficult to carry construction on it. To cope with it, normal methods are used to drain water with the help of pit, lower ground water level and so on. Yet, such practice may result in longer time and be easily affected by weather conditions and construction site, etc. By using braised spodosol the above-mentioned problems can be overcome effectively. This article concentrates on the comparisons between this new practice and normal methods and concludes that braised spodosol is of great use in road construction.
