摘要
介绍了气泡混合轻质土在平兴高速公路台背回填中的应用,阐述了气泡混合轻质土的主要性能、施工工艺及质量控制,分析了其经济效益和社会效益。其应用于台背回填,可降低填土荷载、减少地基附加应力,有效控制填料和地基沉降;强度较高的气泡混合轻质土材料缓解了桥台与路基结合部刚性突变;气泡混合轻质土用于填筑路基,可以减小路基占地面积。
The article introduces the application of the bubble mix light soil in the abutment backfill of Pingxing Expressway, sets forth the main performance, construction technology and quality control of bubble mix light soul, and analyzes its economic benefit and social benefit. Its application in the abutment backfill can reduce the filling load, decrease the additional stress of subgrade, and efficiently control the stuffing and subgrade settlement. The higher intensity of bubble mix light soil material can relieve the rigid mutation at the junction of abutment and roadbed. The bubble mix light soil used for filling roadbed can decrease the roadbed area.
