摘　　要：基于ANSYS的APDL语言,根据邓肯E-B模型的非线性计算原理以及土石坝的非线性静力分析一般方法,编制了土石坝施工模拟的计算程序,并分析了一次加荷与逐层加荷在坝体应力应变计算结果的区别,最后利用程序分别对一种材料和多种材料的堆石坝进行逐层加载模拟计算,通过分析计算结果可知,其计算的应力应变情况符合实际的坝体应力应变分布情况,验证了程序的可靠性,进而实现了土石坝施工过程模拟。By using APDL in the light of ANSYS,according to Duncan E-B model of non-linear calculation principle,as well as the general approach of non-linear static analysis of embankment dams,the article has developed a simulation of earth-rock dam construction calculation program,and analyzed the difference in the stress-strain calculation results of one-time loading and layer-by-layer loading.At last,with the rockfill simulation of layer by layer loading,we calculate the earth-rock dam of one material and of variety of materials respectively.By analyzing the results we can see that the calculation of the stress and strain of the dam is in line with the actual distribution of stress and strain to verify the reliability of the program,thus fulfills one of earth dam construction process simulation.
