Abstract: Pre-compression effects on strength properties and slope stability of cohesive soils were investigated in this paper. Several element tests were carried out on strength of compacted soils, to examine relationships of precompression stress p_c with compaction conditions, fine content of materials, and other mechanical parameters. Strength reduction of unsaturated compacted soils due to wetting were then studied to know appropriate strength parameters for use in short and long-term stability analyses. Also noted were strength reduction properties of cemented soils of natural slope due to initial stress release by cutting and cyclic change of effective stresses caused by up-down movement of water level. Some stability analyses were finally done by use of FEM, by introducing the results obtained above, to investigate the effect of stress history on stability of slopes.
