Lateral Pile-Loading Tests

Tests conducted at Lock and Dam No. 26, Alton, Ill., to determine the resistance under lateral loads of timber and concrete piles, driven in Mississippi River sand, are described in this paper. The work includes descriptions of tests on single piles with heads not fixed, and on groups of four, twelve, and twenty piles with heads fixed in concrete test monoliths. The field data are presented in tabular or graphical form, and the results discussed. In view of the fact that these tests were conducted in only one type of soil, and in view of the many variables involved, no mathematical analysis is included. It is hoped, however, that the results of tests conducted by others may be presented in the discussion.
