The characteristics of pile-rock structure interface considerably influence the load transmission process of the rock-socketed segment of pile. The expressions for pile side friction are established based on the mechanism of sliding dilatancy. An analytical solution for the friction and axial force of the rock-socketed segment are obtained when the surrounding rock is under the conditions of the sliding dilatancy stage. Then the distribution of friction resistance and axial force along the rock-socketed segment are discussed based on the obtained analytical solution and the pile tip load sharing ratio. The load transfer process of the rock-socketed segment of pile is analyzed by conducting a field test on a large-diameter rock-socketed pile. The side friction characteristics in soil and rock are expounded. The calculation parameters are obtained inversely by combining with the theoretical formula. Theoretical calculation result exhibits good agreement with measured data.
