Horizontal loading tests were conducted to observe the behavior of the soil under the ground through a transparent earth tank. In addition, a series of tests by using long piles were conducted to investigate effects of the ratio of the pile diameter to the pile embedment depth on nonlinear behavior of pile-soil structure. Furthermore, simulation analyses of the tests were conducted to obtain better understanding of the test results. The major findings obtained from tests and analyses are summarized as follows; 1) In case of short pile, a slip occurred in the soil around pile ends under small amplitude and at almost the same time, pile head load decreased. The slip extended to the ground surface with increasing displacement. Finally, the ground was deformed like a bump on the ground surface and pile head load became constant. 2) The test results are precisely simulated by 3-D finite element analyses. Plastic strain distribution in the soil of short pile was different from that of long pile. In case of short pile, plastic strain was concentrated in the soil around pile ends under small amplitude. With increasing displacement, the plastificated portion of the soil extended to the ground surface. The extension of the slip observed in the tests is properly simulated as the extension of the plastificated portion of the soil element.
