خلاصه مقاله:
If the properties of the existing soil cannot fulfill the requirements set by the proposed loading conditions, bearing capacity, lateral stability and earthquake induced liquefaction potential, various techniques offer an economical solution for the ground improvement. Soil improvement methods should be determined only after development and analysis of the complete geotechnical record. This record includes groundwater depth, subsoil stratification, soil strength and type, consolidation and compaction characteristics, permeability, liquefaction strength, and dynamic deformation characteristics.The remainder of this paper details these soil improvement techniques. Since several methods can be used in conjunction with each other, combinations should be considered during development of a comprehensive remediation program. Minor variations often occur in the industry; therefore, it is important to work closely with the contractor to fully understand the impact or influence of each variation. In this paper, popular techniques, Deep Vibro Techniques including Vibro Stone Columns; Vibro Compaction and Structural Foundation Elements (Grouted Stone Columns and Vibro Concrete Columns). Then the advantages of them will be explained. By using these information and interrelationships, it is hoped that geotechnical engineers could select suitable method for improving problematic soils and solve their difficulties
