Taking Loess-like silt in areas of Sanmenxia for the study, the test were carried by controlling the different dry density and moisture content of the remolded soil preparing to different state of the samples. The results are as follows, density and moisture content of the test specimen has an important impact on the stress-strain curve of loess-like silt and there will be two kinds of curves such as stress softening curve and stress hardening curve under the different density and moisture content. Partial destruction stress of the test specimen is increasing while the density is increasing and is increasing while the moisture content is decreasing, partial destruction stress of specimen with 7% moisture content is about twice that of specimen with 13% moisture content.
