Abstract
The shear strength parameters of silty clay commonly used in garden landscape fill in Shanghai was investigated. Unsaturated soil samples were prepared with four different compaction degrees and three different water contents. Shear strength of these samples were obtained by direct shear tests, and the influences of compaction degree and water content on the strength parameters were studied. Water contents of a garden fill in Shanghai were investigated in site. Based on these works, advices on the strengths of the unsaturated fill considering the construction condition and climate effect were given.
