摘　　要：该文针对长江口细砂路基压实的技术难点,以室内击实试验为基础,结合现场施工实际,综合考虑细砂填料"多峰"特性、细砂最佳含水率和天然含水率关系、现场施工便易性等因素,明确了长江口细砂路基填筑施工含水率的确定方法。Aiming at the technical difficulties of roadbed compaction by the fine sand at the mouth of Changjiang River,based on the indoor compaction test and according to the field construction practices,the article comprehensively considers the 'multi-peak' characteristic of fine sand stuffing,the relationship of the best water content and the natural water content of fine sand,the usability of field construction and the other factors,and makes clear the method for determining the water content in the filling construction of roadbed by the fine sand at the mouth of Changjiang River.
