摘　　要：结合杭州市滨江区(奥体核心区)闻涛路过池塘段路基施工实践,介绍了路基设计和填筑施工方法。该工艺采用深井降水,塘底铺设块石疏干层加碎石垫层,粉砂土水密法分层填筑,水挖机分层整平、振密,逐层填高至原地面。原地面以上部分按常规路基填筑方法施工,路基施工阶段经压实度与弯沉检测,均满足设计要求。目前道路正式投入使用已经七年多,路况一直较好;该工艺在粉砂土和水资源丰富地区具有施工快速、经济、环保、受气候影响小等优点,可供同类道路工程借鉴。Based on the construction practice of the subgrade along the section of Wentao Road passing by the pond in the core area of Olympic Sports Center in Binjiang District,Hangzhou City,this paper introduces the design and construction methods for the subgrade.This process adopts deep well dewatering,laying a dry layer of block stones and a gravel cushion at the bottom of the pond,and filling the subgrade layer by layer with silty sand soil by the water‑tight method.Each layer is leveled and compacted by a water excavator,gradually raising the fill to the original ground level.The part above the original ground level is constructed by the conventional subgrade filling method.During the subgrade construction stage,the compaction degree and deflection were tested,and all met the design requirements.Currently,the road has been in formal use for more than seven years,and the road conditions have been good.This process has the advantages of fast construction,economy,environmental protection,and less influence by climate in areas rich in silty sand soil and water resources,and can be used as a reference for similar road projects.
