| Abstract: | 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. |
