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.

  1. PRECOMPRESSION With VERTICAL DRAINS: Basic Principles, Type of Vertical Drains, Application, Design Method and Calculation, Installation, Instrumentation, Monitoring, Interpretation, Asaoka Method, and Case Histories.
  2. VACUUM PRELOADING: Surcharging vs Vacuum Method; Execution; Monitoring System; Improved Ground; Application Examples and Case Histories (with projects in Indonesia and Vietnam)
  3. Liquefaction potential analysis: What is Liquefaction; Liquefaction Phenomenon; Liquefaction induced Damages; Identifying Liquefaction Potential; Cyclic Stress Ratio – CSR; Assessing Liquefaction through SPT data; Assessing Liquefaction Potential through CPT data; Liquefaction of Deeper Layer; Calculation Examples.
  4. DYNAMIC COMPACTION: Equipment, Mechanism, Execution procedure, Design Guidlines and Case Histories.
  5. VIBROCOMPACTION – VIBROFLOATATION – STONE COLUMNS: Vibro Compaction Mechanism, Dry Process, Wet Process, Vibroflotation, Vibrocat, Stone Columns, Design Guidelines, Case Histories.
  6. JET GROUTING: Various Grouting Techniques, Equipment, Execution, Formation, Cement and Composition, Application of Jet Grouting.

Gouw Tjie Liong, Ir., M.Eng, ChFC, PhD

Dr. Gouw is a certified Professional Geotechnical Engineer. He has been working in the field of Geotechnical Engineering since 1984. His expertise covering geotechnical investigation, soil instrumentation, deep foundation and excavation for high rise buildings, pile load testing (Static and PDA), pile integrity testing (PIT), sonic logging test, vibration monitoring, slope stability, ground anchors, pumping test, dewatering, micropiles, tunnelling and ground improvement works, e.g. dynamic compaction, vertical drain, vibro-compaction, geosynthetic and grouting. The jobs cover more than 180 projects in Indonesia, Singapore and Srilanka. He has a great passion in the teaching and disseminating of geotechnical engineering knowledge. He serves as lecturer since late 1984. Currently, he serves as Associate Professor at Podomoro University, Jakarta for undergraduate study, and for post graduate students at Universitas Katolik Parahyangan, Bandung, Indonesia. He also conduct regular geotechnical training for engineers. He also chaired the Indonesian Chapter of International Geosynthetics Society since 2006. He has published 80 papers and 22 technical notes.
