摘要
本文对成部粘土的基本性质（物质组成，微观结构，物理、力学、胀缩性质）进行了全面讨论。通过成都粘土石灰土的室内试验，系统分析了成都粘土加入一定量的石灰进行处理后的工程性质变化规律。根据试验研究资料，确定了成都东站扩建工程石灰土基床的最佳（经济）含灰率。
This paper makes a comprehensive expeition of the essential properties of Chengdu clay-grain, chemical compeition, cation exchange,mineralogical composition, microstructure, physical, mechanical,expansive and shrinkable properties. By the way of laboratory test on the lime-soil of Chengdu clay, it analyzes systematically the changeable regulation of Chengdu clay with various lime content. According to the data, it draws a conclusion that what is the most proper (economic) lime content of the lime-soil subgrade at the extension project of Chengdu Railway East Station.
