摘要
以实际拱坝为例,利用生死单元对拱坝的施工过程作三维数值仿真分析。计算拱坝在考虑坝体分缝自重时,坝体的变形及应力情况,并与将拱坝自重整体考虑时的计算结果进行了对比分析。研究结果表明,考虑坝体分缝自重时的结果较为真实合理,能较好地模拟施工仿真过程。
In this paper, the authors simulated and analysed the construction process of an actual arch dam by using 3-D numerical method and 'birth and death' element function. The deformation and stress were computed with consideration of jointed deadweight of dam set beforehand, and compared with the result obtained in consideration the whole deadweight of dam mass. The analysis result shows that the calculation result is reliable and reasonable with consideration of jointed deadweight of dam. This method is suitable for simulating the construction process of arch dam.
