Abstract：The analytical method of load transfer is adopted to study the load transfer mechanism of rock-socketed filling pile in this paper. According to the different behaviors of work-softing or work-hardening of soil in engineering practice，a uniform load transfer model is established for various types of soil or rock. Based on this model，the relation formula between the settlement and load of pile top is deduced，which can consider side resistance force of soil (rock) along the pile shaft，the end resistance at the bottom and the influence of slime. As a result，the vertical bearing capacity of rock-socketed filling pile may be determined by the settlement of pile top. The calculated results by the presented method show a good agreement with those measured from test pile.
