摘　　要：提出了三维有限元、无界元与节理元的耦合系统，利用该系统模拟并分析了含有 节理夹层不均匀坝基的应力和位移分布情况．结果表明，该系统既反映了实际单元情 况，又具有良好的精确度．A coupling system of three dimensional infinite or finite elements and joint infinite or joint finite elements is presented. This coupling system is used for simulating dam foundation with tectonic faults and anaiysing the stress and displacement result. The result shows that the system can successfully simulate the tectonic faults and can give a more accurate result than that of the joint elements ordinarily used.
