罗中铁路岩盐路基填筑施工技术

罗中铁路穿越罗布泊盐湖区,需要用岩盐作为填筑材料填筑路基。通过施工工艺研究、填筑质量检测试验、沉降观测等方法对岩盐路基填筑技术进行了研究,在基底处理、洒卤水碾压、摊铺晾晒工艺上进行了改进,较以往施工经验有所不同。该技术安全可靠,取得了良好的社会效益与经济效益。

Rock Salt Subgrade Filling Construction Technology of Luozhong Railway

Luozhong Railway crosses Lop Nor Saline Lake area and rock salt is needed for filling subgrade. This paper studies rock salt subgrade filling technology by the methods of construction technology, filling quality testing, settlement ob-servation, etc. , improves base treatment, sprinkle brine rolling, and paving drying technique, which differs from previous construction experiences. It demonstrates that this proposed technology has great safety and reliability, and would achieve significant social and economic benefits.
