Aimed　at　problems　lying　in　the　existing　m　methods　for　calculation　of　laterally　loaded　piles　installed　in　multi-layered　soils,　the　finite　difference　method　and　the　pole　system　finite　element　method　of　elastic　foundation　beam　with　elastic　links　were　presented　in　order　to　compute　the　displacements　and　internal　forces　by　adopting　actual　modulus　of　subgrade　reaction　of　layered　soils.　The　computations　and　postprocessing　of　images　for　displacements　and　internal　forces　of　piles　were　programmed.　It　was　shown　by　computation　and　comparison　of　practical　examples　that　the　calculated　results　by　the　two　numerical　methods　coincided　very　well.　Meanwhile,　the　two　methods　were　more　precise　and　efficient　than　the　existing　conversion　methods　of　subgrade　modulus.　Therefore,　they　could　be　directly　applied　to　the　design　calculation　and　analysis　of　laterally　loaded　piles　installed　in　multi-layered　soils.
