摘要
结合宁波市某城市道路深厚软土地基处理与路基设计工程实践,总结了路面面层、垫层与基层、路面结构层的设计经验,从路基临界填土高度、桥头填土、工后沉降、塘渣填筑厚度、土工格栅和技术标准等方面就深厚软土地基处理与路基设计等问题进行了探讨。
Combined with a city road deep and thick soft soil foundation treatment and design of subgrade engineering practice in Ningbo,the design experience of pavement surface layer,pad layer and grass-roots,and pavement structure layer was summarized.The problems of deep and thick soft foundation treatment and design of subgrade were discussed,from the aspect of subgrade critical filled soil height,bridgehead filled soil,post construction settlement,pond slag filling thickness,geogrid and technical standards.
