摘要：
In order to discuss the calculation model and design method of double-row sliding piles without a connected beam, a laboratory simulation test was carried out. According to pile top displacement, pile body deformation, and pressure distribution, the ratio of landslide thrust sharing between front and back piles is about 1:1.6. It is found that the thrust of the landslide behind the pile is triangular, and the total resistance is parabolic. A calculation model is presented which takes the plastic hinge above the slip plane as the zero shear directional support. The pile is divided into two parts, the upper part and the lower part, and the cantilever pile method and the finite difference method are used for calculation, respectively. This method can calculate the internal force accurately, and it is verified by an engineering example.
