| 内容記述 | According to the field observations the bearing capacity of a deep foundation in sands is not proportional to depth and is smaller than the one expected by the current plastic theory. Then the authors carried out a model loading test of a pile in sands confined by the high pressures similar to the ground stress conditions. They show that the bearing capacity is smaller because the angle of shear resistance under the high pressure becomes lower due to the crush of sand grains. They established a new formula to estimate the angle of shear resistance as the function of the relative density and the break pressure of sand grains, and calculated the bearing capacity factor for the angle. The following conclusions are presented for a deep foundation. 1) The type of load-settlement curve is controlled by the ratio of the lateral pressure to the vertical pressure in sands. And its ultimate bearing capacity depends on but is not proportional to the over burden pressure. It is smaller than the one expected by the current existing theory. 2) The bearing capacity factor is smaller than the half of the one for a shallow foundation in sands. 3) The bearing capacity of sands becomes linear with depth according as its relative density becomes lower. |
