Calculation of Landslide Thrust behind Double-Row Long-Short Piles

Double-row piles are an effective measure for the management of large landslides, and double-row long-short piles are a new type of such piles. At present, research on the landslide thrust behind double-row long-short piles is limited. On the basis of a model of a Winkler beam on an elastic foundation, and fully considering the compatibility deformation between the load and fixed segments, a calculation method for the landslide thrust behind rigid double-row long-short piles is proposed. The theoretical calculation result is found to agree with the monitored data of the model test. Therefore, the calculation of the landslide thrust of double-row long-short piles is feasible.
