摘　　要：本文研究杭州钱塘江沿岸工程开挖废弃的砂质粉土经处理后,用于市政道路路床修筑的应用方案。研究将基于室内实验进行,是后续实验研究的前序部分。室内实验针对某固化剂及某混合料进行了最佳配合比研究,将实验结果进行交叉口对比。并根据经济分析的结果,得出基于室内实验的最佳配合比。该成果将为后续现场实验打好理论基础,并缩小现场实验的实验范围,提高研究效率。This paper studies the application scheme of sandy silt discarded by excavation in projects along the Qiantang River in Hangzhou for municipal road bed construction after treatment.The study will be conducted based on indoor experiments and is a preliminary part to subsequent experimental studies.In the indoor experiments,the optimal mixing ratio of a curing agent and a mixture is studied,and the experimental results are crossing compared.Based on the results of economic analysis,the optimal mixing ratio based on indoor experiments is obtained.This achievement will lay a good theoretical foundation for subsequent field experiments,reduce the experimental scope of field experiments,and improve research efficiency.
