Tóm tắt: Design of a piled foundation rarely includes a settlement analysis and is usually limited to determining that the factor of safety on pile capacity is equal to an at least value. This approach is uneconomical and, sometimes, unsafe. Every design of a piled foundation should establish the resistance distribution along the pile, determine the location of the force equilibrium (the neutral plane), estimate the magnitude of dragload from accumulated negative skin friction at the neutral plane, evaluate the length of the zone where the shear forces change from negative to positive direction, establish the load-movement relation for the pile toe and the load distribution in the pile at the time that settlement becomes an issue for the design, and, finally, perform a settlement analysis. The settlement analysis of a piled foundation must distinguish between settlement due to movements caused by external load on the piles and settlement due to causes other than the load on the piles. A fundamental realization of the design approach is that pile toe capacity is a misconception. Each of the mentioned points is addressed in the paper, and a design approach for the design of piled foundations and piled rafts is presented. Examples and case histories are included showing the distribution of measured and calculated resistance distribution along the piles and settlement of soil and piles.
