灰土固结改良技术在过湿软土路基中的应用

Application of Improvement Technology by Lime-soil Consolidation in Overwet Soft Soil Subgrade

通过对过湿软土路基进行掺加石灰固结改良,达到了设计技术指标,在矿料匮乏的情况下,可替代宕渣。该技术不仅解决了路基土源问题,而且减轻了弃土占用土地和污染环境,解决了长期以来依靠宕渣作为湖州地区主要路基填料的单一性问题和困扰,具有实质的综合经济和社会效益。

In this paper,the overwet soft soil subgrade is improved by lime-soil consolidation to achieve the design technical indicators,which can be used to replace slag in the case of shortage of mineral resources. This technology can not only solve the problem of subgrade soil source,also can reduce the occupation of land and environmental pollution. It solve the problem and trouble that we have relied on slag as the main subgrade filling for a long time in Huzhou area,and will have good comprehensive economic and social benefits.
