Design Load of Bored Pile Laterally Loaded

From the testing data of bored piles compiled, several characteristic curves have been plotted and studied. It is found that the load-stress curve serves well for the purpose to ascertain various states of flexural stresses in a pile section. On such curve, that point prior to the load that will cause the pile rapidly to fail is defined as critical point, which appears to be a satisfactory criterion for the determination of pile's design load.
