Study on Shear Rate Effects of Reticulate Red Clay

Abstract:

Article Preview

Direct shear tests were performed to study the shear rate effects of reticulate red clay around Dongting Lake. In the direct shear tests, four sets of undisturbed specimen of reticulate red clay were sheared under the different vertical pressure of 50kPa, 100kPa, 200kPa and 300kPa. Specimens were sheared with six different shear rates of 0.04mm/s, 0.02mm/s, 0.01mm/s, 0.007mm/s, 0.004mm/s and 0.003mm/s under each vertical pressure. Test results show that: (1) shear strength of reticulate red clay increases along with the vertical pressure; (2) shear rate effects of reticulate red clay are affected by vertical pressure significantly; (3) due to its reticulate structure of reticulate red clay, it shows some differences in shear rate effects comparing with other clay.
