摘　　要：高速公路的路基施工对土源的需求较大、对土源的质量要求较高。而对于土地资源匮乏的地区如何进行高速公路路基施工是迫切需要解决的问题,利用长江口细砂填筑路基不仅可以就地取材,降低工程造价,而且可以减少道路修筑对当地资源的消耗、保护耕地、避免水土流失,在强调资源的合理利用和社会可持续发展的今天尤其具有现实意义。论文结合上海S32高速公路填砂路基施工实践,探讨了填砂路基施工的关键问题和质量控制要点。Freeway subgrade construction required greater demand and higher quality on soil sources.And it is an urgent need to address the problem that how to process freeway subgrade construction in the region with scarcity of land resource.Using fine sand of Yangtze River to fill subgrade,not only reducing the construction costs through utilizes local materials,but also reducing the consumption of local resources,protecting land and avoiding soil erosion.This is very meaningful contribute to social sustainable developments and high efficient using resource.This study analysis the critical issues and quality control points for sand-filling subgrade with case study of Shanghai S32 freeway construction practice.
