本文针对黄河大堤存在的裂隙、孔洞等隐患,采用有限元渗流方法对各种可能存在的隐患进行模拟,研究不同隐患对黄河大堤的渗透稳定性的影响,同时对黄河大堤采用的放淤固堤的加固措施进行数值模拟研究,结果表明:各种隐患的存在加大了黄河大堤渗透破坏的可能,而放淤固堤的加固措施能够有效地减小这种可能,使大堤的渗透稳定性明显提高。
In this paper, according to the hidden troubles such as fissures and holes existing in the Yellow River dike, the finite element seepage method is used to simulate the potential hidden dangers, and the influences of different hidden dangers on the seepage stability of the Yellow River dike are studied. Meanwhile, The results show that the existence of various hidden dangers increases the possibility of infiltration and destruction of the Yellow River dike, and the reinforcement measures of the silt dipping and embankment can effectively reduce this possibility, and the infiltration stability of the dike is obviously improved.
