| Abstract: | The recent development in soil mechanics is presented.The history and the significance of research on mechanics of unsaturated soil are expounded.In association with expansive soil problem involved in the South-to-North Water Transfer project,the shear strength theory of unsaturated soil is applied to experimental study on engineering practice by way of trial.Tests of relation between absorbing force of soil and its water content and tests of triaxial shear strength are conducted in laboratory.Absorbing force distribution of natural expansive soil in side slope are investigated in field,and various instruments and methods for measuring absorbing force are compared.These researches accumulate experiences for engineering application of unsaturated soil theory. |
