Abstract
Low-plasticity silt has been found susceptible to liquefaction in recent earthquake reconnaissance. As silt is less permeable than sand, a different excess pore water pressure dissipation mechanism could take place. This may have an effect on the cyclic strength at different loading rates, although the influence on loading rate is neglected in general. According to the ASTM testing standard, a typical loading rate for cyclic triaxial tests should be set between 2 and 0.1 Hz. However, it is evident from the test results in this study that various loading rates lead to different cyclic resistance curves. In this paper, we present a series of dynamic cyclic triaxial tests on reconstituted silt specimens with silica silt and the Tieliku silt which is in situ silt under various loading rates. It is concluded that the low-plasticity silt may be rate-dependent in cyclic triaxial testing.
