基于气泡混合轻质土作为路基填料的优点,介绍上覆硬壳层软基气泡混合轻质土的施工技术及流程,结合工程实例,验证了上覆硬壳层软基气泡混合轻质土在路基填筑中应力扩散、沉降小的技术优点。
Based on the advantage of foamed mixture lightweight soil as a subgrade filling,we presented the construction technology and process of foamed mixture lightweight soil on hard shell lying on soft soil foundation. Connecting with the engineering examples,we confirmed that foamed mixture lightweight soil on hard shell lying on soft soil foundation which could dispersive stress and reduce the settlement in subgrade filling as it' s advantages.
