This is the introductory course of ground improvement techniques for marginal and problematic soil. The content includes the basics of laboratory and in situ tests for geotechnical projects. Then, surface compaction, admixture stabilization and deep densification are covered. Ground modification by consolidation and vertical drains are then covered. Various types of insitu reinforcement techniques such as stone columns, soil soils are introduced.

CILO-1: Recognize and distinguish the use and importance of various soil improvement techniquees in engineering projects. CILO-2: Outline various laboratory and in situ tests for soil improvement projects. (POs: a,e) CILO-3: Recognize the operation of surface compaction and solve problems for its quality control. (POs: a,c,e) CILO-4: Recognize the operation of admixture stabilization and computesthe use amount for engineering projects.(POs: a,c,e) CILO-5: Recognize the operation of deep densification and give example of its quality control method.[POs: a,e] CILO-6: Recognize the operation and compute the settlement about preloading and vertical drains for soft soil improvement.[POs: a,c,e] CILO-7: Recognize the operation and quality control of insitu reinforcement such as soil nail, stone column and design their reinforcement scheme .
