Soil Stiffness For JAKARTA Silty And Clayey Soils

Written by Gouw Tjie Liong, Ir., M.Eng, ChFC, PhD. Posted in GTL Paper

ABSTRACT: The upper layer of Jakarta soil is mostly silty and clayey types, which is very compressible and very sensitive to the loads applied that could caused damages to the building. These problems are usually not caused by the strength but more on the deformation properties of the soil. This research is aim to help the engineers in predicting the soil deformation modulus by getting the right E-value from an empirical correlation.

In this research, data are collected from the soil investigation companies in Jakarta. The excel spreadsheet program was used in data processing and also to develop the correlation to find the E-value. At the end of the research the relevant conclusion were drawn to get the proposed correlation between E vs N value and E vs PI.

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.
