摘　　要：在桩周土界面引入边界元, 能较好地模拟桩土共同作用工作状态, 简化传统的数值解法步骤. 本文通过实例计算分析得到了比较满意的结果, 证明了有限-边界元法的可靠性和实际应用价值.The boundary element on the boundary between pile and soil around pile shaft to imitate their reactionis recommended and, the traditional numerical methods are simplified. Through a careful calculation and analysison a practical case, some satisfactory solutions are obtained to prove the reliability and the practicality of thismethod.
