6～9月为鲁西北地区集中降雨时期,又是施工黄金季节,寻求高含水量路基填料的科学处理及合理利用方法是该地区路基修筑技术的关键。文章在摊铺晾晒、掺入生石灰的基础上,结合当地资源状况,提出粉煤灰-生石灰双掺改良过湿土工程措施,有利于改善路基压实特性,并大幅度地提高了路基填料的强度和稳定性,经工程实践验证,该项措施技术经济性较好,并且有利于工业废弃物的利用。 From June to September, it is the concentrated rainfall period in the northwestern Shandong and the golden season of construction. The scientific treatment and reasonable utilization of the roadbed filler with high water content is the key to the subgrade construction technology in this area. Based on the paving and drying, and the incorporation of quicklime, combined with the local resources, the paper puts forward the engineering measures of improving fly ash and flyash through double wetting so as to improve the subgrade compaction characteristics and greatly improve the filling of subgrade Strength and stability, verified by engineering practice, the technical and economic benefits of this measure is good, and is conducive to the utilization of industrial waste.
