It is preferable that the piled raft foundations in poor soils are designed in such a way that the total and differential settlements are limited to an acceptable level. In order to calculate the settlement process of building quickly and easily, we have already proposed a practical method named PASS. The purpose of this paper is to improve the accuracy of the calculation by PASS. We introduce the new effective diameter of pile, which is considered the pile compressibility and the finite soil layer, in the method. The parametric studies of the piled raft foundation as well as the single pile with various values are performed. As a result, we conclude that PASS is of much practical use to predict the total and differential settlements of the piled raft foundations, even the cases the Young's modulus ratio(pile/soil) and the layer ratio(soil thickness/pile length) are relatively small.
