| Abstract: | 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. |
