| 摘 要： | 采用劈裂灌浆防渗加固技术来改进坝体的稳定性，是堤坝加固领域的一种非常有效的加固方法。根据广东某水库的实际情况，采用三维快速拉格郎日分析（FLAC3D）方法对坝体灌浆前后的稳定性进行了数值模拟分析。通过模拟分析可知，三维快速拉格朗日分析方法可以较好地模拟劈裂灌浆过程中土体材料的弹塑性力学行为和施工过程，且分析结果与实际观测结果吻合。

| Abstract: | The stability of a certain dam is improved by the method of splitting grouting, which is a very effective reinforcement method. The advanced FLAC3D method based on 3-D explicit finite difference method, is used to analyze the stability of a certain dam in Guangdong Province before and after grouting. The simulation and analysis practice shows that the advanced FLAC3D method is suitable for stimulating the stability of grouting dam. The conclusion of analysis is consistent with the in-situ observation. |
