模型実験に基づく,中間土中のNon-displacement pileの先端支持力

抄録

Model tests of Non-displacement piles in hard cohesive soil and sand were performed in which void ratio and drained shear strength were adopted as factors. The results of these model tests and the model tests in hard clay which were published in 1998(cf.Ref. 1) led to the following conclusions,: (1) The void ratio which changes greatly the relationship between the point bearing capacity and settlement of the pile exists between 0.7 and 1,0. It is very important to the behavior of the pile tip (2)The proposed approach for estimating settlement less than about 20% of pile diameter is generally consistent with model test results.
