砂地盤中の Non-displacement pile 先端部地盤の破壊機構

抄録

Two series of the modal pile loading tests were carried out to clarify the failure mechanism of the soil mass under the pile base in sand. In the first series of the model pile loading tests (Test-I), the displacement of single pile was observed by X-Ray pictures. The second series of the model pile loading test (Test-II) were carried out to observe the shear failure patterns and the particle breakage of the sand under the pile base. The lists of the pile loading tests and load-settlement curves for Test-I and -II are shown in Table 1, 2 and Fig. 1, respectively. The properties of sands used in the tests are shown in Table 3.
