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。
Based on APDL language of ANSYS, according to the non-linear calculation principle of Duncan EB model and the general method of nonlinear static analysis of earth-rockfill dam, the calculation program of earth-rockfill dam construction simulation is compiled and the effects of one-time loading and layer- The difference between the calculation results of body stress and strain, and finally, the program is used to simulate the rockfill dam with one kind of material and multiple materials layer by layer. According to the calculation results, the calculated stress and strain are in accordance with the actual stress and strain of the dam Distribution, verified the reliability of the program, and then realized the construction process simulation of earth-rockfill dam.
