杭甬高速公路杭州段部分路段,由于缺乏良好路堤填料,采用粉性土和清岩碴填筑,为保证路基强度和稳定性,采取严格控制含水量和压实度,精心施工,加强路基路面排水设施和采用土工布防止粉性土流失等措施,使路堤质量得到保证。本文介绍了具体做法和经验教训。 Due to the lack of good embankment packing and the use of silt and Qingyan ballast filling, in order to ensure the strength and stability of subgrade, the water quality and compaction degree of Hangzhou-Ningbo Expressway should be strictly controlled and meticulously constructed to strengthen the roadbed pavement Drainage facilities and the use of geotextile to prevent the loss of soil and other measures to make embankment quality assurance. This article describes the specific practices and lessons learned.
