摘要
对秦沈客运专线粉黏土进行了大量的原土和改良土室内、外及现场填筑试验 ,取得了各土源大量数据。通过试验结果的分析 ,对粉黏土的一些物理力学指标之间的关系进行探讨 ,初步确定了对粉黏土的适用性判别标准 ,提出粉黏土物理改良方法及适用条件 。
A large number of indoor, outdoor and site tests were carried out of original and modified silty clay, and a large quantity of data were collected. The relationship between the physical and mechanical index of the silty clay was discussed through analysis of test result, and the identification standard for silty clay applicability was defined. The physical modification method for silty clay and applicable conditions, and the strength design method and steps for chemical modification of silty clay were put forward.
