The lateral deflections for the lateral tests in soft clay at Sabine, for example, did not exceed about 20% of the pile diameter. In addition, the Mars design was conservatively designed by assuming...

... under static and cyclic loading have been performed for Conoco and other industry sponsors. Based on the results, methods were developed for the design of friction piles in normally consolidated clays (Bogard and Matlock, 1990a; Bogard, Matlock, and Chan, 2000). The design methods include consideration...

The data reported herein demonstrate that while the cyclic criteria are appropriate for working stress analyses...
