This paper presents (a) constitutive models such as hypo-elastic models and elastic visco-plastic models, (b) methods for calculating the settlement of clayey soils in one-dimensional (1D) straining, (c) equations for nonlinear creep and compression of clayey soils in 1D straining, (d) development of lab testing facilities such as a double cell triaxial apparatus, a true-triaxial loading device, a direct shear box for testing the interface of a structural element and an unsaturated soil with suction control, and a soil nail pullout box, and (e) development of optical fiber sensing technologies for geotechnical monitoring. From the above presentation, the main conclusions are summarized in this paper.
