摘　　要：近年来随着筑坝技术的提高，面板堆石坝在200米级已经成功实现，现在正在朝着300米级的方向发展，土石坝堆石料是高度的分线性材料，随着坝高的增加坝体应力应变规律如何、200米级的筑坝理论能否继续沿用等等这些都值得研究。本文就依托拟建项目古水电站（面板堆石坝方案，坝高3100米）借助有限元软件ANSYS及其自带~APDL命令语言进行二次开发，计算分析坝体的应力应变规律，并与清华CAL2计算成果进行对比分析，从应力应变静力分析看300米级的面板堆石坝是可行的。As the technique for dam construction has been enhanced over recent years, concrete faced rock-fill dam with a height of 200m was successfully built and now, a goal of 300m is developed and efforts being paid thereto. Because rock filling materials for dam are highly nonlinear, such topics, as stress-strain rules of the dam as height kept increasing, whether building theory for 200m dam is suitable for further application and so on is worth studying. This paper, based on the construction of Gushui hydropower station （Following concrete faced rock fill plan, 310m high）, a scheduled project, calculates the stress-strain rules of the dam with the help ofANSYS, a Finite Element Software and its secondary development, which is carried out by the APDL command language in the software. Calculated results are compared with that calculated by Qinghua CAL2, and from the stress-strain analysis, building a concrete faced rock fill dam with a height of 300m is possible.
