摘　　要：为解决南水北调中线工程填筑土料严重不足问题,拟采用中细砂改性技术方案。根据南水北调中线京石段应急供水工程S3、S12、S19标段中细砂改性室内试验成果,总结分析改性土的物理力学指标与掺加材料、试验龄期之间的相关关系,为工程设计进行方案比选提供必要的物理力学参数。In order to solve the serious shortage of filling soil in the middle route of South to North Water Transfer Project,the medium fine sand modification technology was adopted. According to the results of laboratory test on modification of medium fine sand of S3,S12,S19 tenders in emergency water supply project of Beijing Shijiazhuang section in middle route of South to North Water Transfer Project,the correlation between physical mechanical indexes and materials,test ages of modified soil are summarized and analyzed,the necessary physical and mechanical parameters are provided for scheme comparison for engineering design.
