摘　　要：由于弹性桩能较好地承受水平荷载,因此应用广泛。以某基桩为例,采用有限元法研究其工作性状,结果表明:在水平荷载作用下,弹性基桩的水平位移在桩顶处最大,且随着深度增加而逐渐减小;桩身下部发生挠曲变形,位移较小,土体对桩的嵌固作用明显;弯矩先增大后减小,最大弯矩发生在桩长1/4处;应力分布与弯矩基本一致。Elastic pile, which can better bear horizontal load, is widely used. Its working behavior was studied based on finite element method, taking a pile for example. It shows, under horizontal load, the horizontal displacement of elastic piles at the top of the pile at the maximum, with the depth increasing gradually decreases. The lower part of pile deflection,the displacement is small,and the soil on the pile of fixed effect is obvious. Moment increased first and then decreased, the moment at the long 1/4 pile is maximum. Stress distribution and moment is consistent.
