Popis:	A series of vertical load tests are performed on model piles with enlarged base bulb embedded in a medium dense sand filled in a soil chamber of 1000mm diameter. The model pile used is a nodular pile consisting of 114mm diameter double steel tubes with two nodes around the outer tube. The effects of the size and shape of the base bulb are investigated to find the behavior of the vertical load transfer and the fracture patter of the base bulbs. Detail measurement of strain gauges on the pile shaft show that the load share by parts of the pile varies with the increase of the settlement. The fracture pattern of the bulbs excavated after load tests explains well the measured load settlement characteristics.
