Soil-water characteristic curve for unsaturated loess considering temperature and density effect is studied by test. The test data show that the variation of soil density
compared with variation of soil temperature
can result in great change of soil-water characteristic curve. For loess sample in certain water content
the change of matrix suction resulting from variation of soil temperature is less in bigger water content
and is more in lower water content. The more is the variation of soil temperature
the more is the change of matrix suction. After analyzing the test data
taking the soil density and temperature into account
the formula is obtained to determine the matrix suction of unsaturated loess. The test and calculated data verify the reliability of the formula.
