STATRAPID – ALTERNATIF UJI BEBAN STATIK

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

ABSTRAK: StatRapid merupakan suatu teknik uji beban pondasi tiang yang relatif baru, yang dikembangkan sebagai alternatif uji beban statik dan uji PDA. Dalam uji StatRapid ini, beban plat baja modular yang dikombinasikan dengan sistem pegas dijatuhkan dari ketinggian tertentu, menumbuk dan menekan kepala tiang ke dalam tanah. Durasi tumbukan dibuat cukup lama sehingga tiang berperilaku kuasi-statik. Masa beban tumbukan yang diperlukan hanya 5% dari masa yang diperlukan untuk uji beban statik. Saat tumbukan terjadi, gaya, pergerakan, dan percepatan kepala tiang diukur. Dari pengukuran tersebut perilaku beban vs penurunan dan beban statik yang ditimbulkan dapat diturunkan. Makalah ini membahas metode dan interpretasi serta perbandingan uji StatRapid ini dengan uji beban statis. Disimpulkan bahwa StatRapid merupakan sebuah alternatif yang cukup baik bila diperlukan uji beban yang cepat dan handal.

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.
