Osterberg CELL for Load Testing Drilled Shafts and Driven Piles.

PB95209508

Publication Date	1995
Personal Author	Osterberg, J. O.
Page Count	88
Abstract	The Osterberg Cell (CELL) technology is a new concept of load testing conceived to revolutionize conventional deep foundation load testing, facilitate future refinement of design methods, and realize significant cost savings. CELLs as large as 1.2m (4ft) in diameter have been used, and load tests to an equivalent top load of greater than 53,400 kN (6,000 tons) have been performed. Installation, testing, results and the types of applications are discussed in the text. Descriptions of many job applications are given in the appendices. Calibration and accuracy of the CELL and test methods are reviewed. Advantages and limitations of the CELL are compared to conventional load testing methods.
