| Outline of Final Research Achievements |
The pile bearing capacity consists of pile end bearing capacity and pile skin friction. These days, the rate of pile end one to the total one. So it is necessary to evaluate the pile end one accurately. The pile end is settled on the supporting layer. When the strength of the soil and the thickness of the layer are enough, we can expect the adequate pile end bearing capacity. But if the thickness is small or the supporting layer includes a clay layer, the pile end capacity decreases. There is some evaluation method of the decrease, but the accuracy of them has not been investigated. This research is for investigating the accuracy of the methods based on the result of the model pile tests.
