This paper describes results of scaled model test for bearing capacity of nodular cylinder pile as compared to non-nodular cylinder pile. Model piles on the scale of one-fifth are tested for penetration in sand pressured by the vertical and horizontal stresses. The movement of sand around the pile is observed by X-ray photograph. The test results are summarized as follows. (1) The lowest nodule part of a pile works in the same way as the pile tip. Other nodule parts also work similarly to the pile tip in small settlement. But in large settlement, a cylindric slip surface with diameter larger than the nodule is formed around the pile. (2) The point bearing capacity of a nodular pile is 75 percent of the capacity of a non-nodular pile. (3) The shaft capacity of a nodular pile is about 2.5 times as much as that of a non-nodular pile. The shaft capacity of a nodular pile is about twice as much as shear resistance of cylindric slip surface.
