Background: Soft compressible clay induces large total and differential settlement to the structures built above. Construction on loose sands and high seismic region may face catastrophic liquefaction. To mitigate those problems and design a safe and economical foundation, a proper understanding of the settlement problem and the liquefaction potential is a pre-requisite, followed by the selection and design of suitable ground improvement method. This short course is designed to introduce and to train civil/structural/geotechnical engineers with the design, execution and monitoring of suitable ground improvement techniques. Exercise with case histories on real projects shall be given.
Course Contents: Covering theoretical design calculation,execution, monitoring and interpretation. Practice design and data interpretation session shall be given.
