It　is　difficult　to　accurately　determine　the　stiffness　coefficient　of　foundation　spring　in　the　response　displacement　method.　Furthermore,　different　foundation　springs　are　not　relevant,　and　the　interaction　between　the　structure　and　the　soil　cannot　be　actually　reflected,　causing　error　in　the　load　distribution　on　the　soil-structure　contact.　Taking　the　foundation　spring　as　the　research　object,　an　improved　response　displacement　method　is　proposed,　abandoning　the　traditional　loading　method　in　the　finite　element　analysis　process　and　loading　the　force　all　around　the　structure　to　solve　the　stiffness　coefficient　of　foundation　spring.　Compared　with　the　existing　response　displacement　methods,　the　calculated　results　of　the　improved　method　is　reasonable,　and　the　proposed　method　has　higher　computational　efficiency.
