Abstract	In order to explore the displacement evolution of a creeping landslide stabilized with piles, an analytical model is proposed in this paper. Mechanical behaviors of the sliding surface and the sliding layer in the model are assumed to be visco-plastic and elastic, respectively. Equilibrium of a soil slice in the sliding layer is applied to establish the differential equation, which can be solved as a non-homogeneous heat equation. The displacement of the soil around stabilizing pile is considered as boundary condition at the bottom of the sliding layer, and the stress applied on the upper boundary of the sliding layer is assumed to be a constant. Therefore, the displacement solution of the sliding layer was obtained by solving the non-homogeneous heat equation with the mixed boundary conditions. Subsequently, the analytical model is validated against the monitoring data from Hongyan landslide in China. A good agreement between the measured displacement and the calculated displacement by the proposed model is obtained. Finally, the pile-stabilized region with respect to time, influences of stress distribution in the sliding layer, and the water table on the proposed model are discussed in this paper.
