The author also owes his greatest gratitude to the committee members: Dr. Joseph Tedesco for sacrificing his time and for his critical insights into the research, Dr. John Davidson for his ideal academic instructions and for being a role model in and out of the classroom, Dr. Paul Bullock for the invaluable assistance in the field testing and the extremely instructive discussions in his office, and Dr. Steven Detweiler for his contribution to this research by expressing different points of view. The author is also indebted to the personnel of the Florida Department of Transportation, especially the project coordinator Peter Lai, for their support and technical assistance. The author would like to express his gratitude to the personnel of Turner, Inc. at the University of South Florida site, the personnel of Applied Foundations Testing, Inc., especially Mike Muchard and Don Robertson, and the personnel of Pile Equipment, Inc. at the Green Cove Springs site. The author would like to thank all those at the University of Florida, especially Brian Anderson, Chris Kohlhof, Danny Brown, Bob Konz, Hubert Martin, and Tony Murphy who assisted in many ways throughout this work. iii The author appreciates the unforgettable help from the Geotech graduate students Jason Gowland, Joshua Logan, and Scott Jacobs. The Geotech Fall ’99 crew, especially Rodrigo Herrera, Victor Alvarez, Michael Kim, and Thai Nguyen will always be remembered for the exchange of knowledge and the valuable discussions on daily events. The author also thanks the younger and exuberant Geotech graduate students, especially Zhihong Hu and Minh Le for improving his computer skills during the writing of this dissertation. The author is grateful to professors M. Sezaki, H. Yokota, and F. Imai of the Department of Civil and Environmental Engineering, Miyazaki University, Japan, to professor N. Cristescu of the University of Florida, and to the staff of the Agency of Daiho Corporation in Madagascar. Last but certainly not least, the author would like to present his most heartfelt acknowledgements to his father for education and principles, to his mother for caring and understanding, to his brothers and sisters for sound advice and for cheering him up all the time, and to his long-time best friend Noriko Goto for encouragement, support and patience. iv TABLE OF CONTENTS page

  • A.1 Statnamic the Statnamic Load Test
    A.1 Statnamic The Statnamic Load Test (STN) has been developed by TNO and Berminghammer Foundation Equipment. The principle of the test is based on the launching of a reaction mass by burning fuel in a closed pressure chamber. This reaction mass is only 5% of the weight needed for a static load test. Loading is perfectly axial. Figure A1-1 represents the successive stages of a Statnamic load test. Phase I is the situation just before launching. A cylinder with pressure chamber has been connected to the pile head and the reaction mass has been placed over the piston. In phase II the solid fuel propellant is ignited inside the pressure chamber, generating high-pressure gases and accelerating the reaction mass. At this stage the actual loading of the pile takes place, as an equal and opposite reaction force gently loads the pile. The applied pile force, displacement and acceleration are directly monitored. The upward movement of the reaction mass results in space, which is filled by the gravel (phase III). Gravity causes the gravel to flow over the pile head as a layer, catching the reaction mass and transferring impact forces to the subsoil (phase IV). Available device loads are 1, 2, 3, 4, 5, 8, 16, 20, 30, and 40 MN. The testing range is between 25% and 100% of the device load. Devices of 100MN are under design and will be manufactured.. During the test the reaction mass reaches a height between 2-3 m and then falls back. For high loads of 5-30 MN, gravel is used to catch the reaction mass.
