The FEM model of laterally loaded super long pile in double-layered soil is built by ANSYS, based on which, the soil resistance under the pile-soil interaction and the moment distribution and shaft deflection of super long pile are simulated. The distribution of soil resistance along pile and its contribution to the bearing capacity are discussed in detail. And, the lateral properties of super long pile under various horizontal loads, elastic modulus ratio of double-layered soil and length-diameter ratio are also discussed. The results show that, to a certain depth, the radial distribution of vertical side friction, tangential friction and soil resistance along the pile present different curves. And to the same position in the circumferential direction, the maximum soil resistance exists in the pile head. The moment distribution and shaft deflection along the pile decrease as a result of elastic modulus ratio's increase. The laterally loaded super long pile exists effective length. The optimal length-diameter ratio leads to the optimal performance. There exists inflection point and zero displacement point along the pile body.
