摘要：

衢江小支流较发育的河溪交织如网 ,千年漂流并沉睡的河滩料取之不尽。这种天然级配砂砾具有级配良好、粒径易控制、易碾压成型、透水性好等特点。本文主要阐述采用天然级配的河滩料填筑路基的施工工艺、检验方法及效果

The well developed riverlets and brooks in the tributaries of the Qujiang River are anastomosed into a network and the drifting deposit in the river flat is always available for use.The river deposit,which is made up of naturally graded sand and gravel,is characterized by its well gradation,easy control of its particle size,easy compaction and good permeability.The paper presents a description of the technology,method of checking and inspection,and effect of using naturally graded river flat deposit as the fill material in subgrade
