吸力锚的负压沉贯安装是其主要特征，对吸力锚承载能力的分析必须要考虑负压沉贯的影响。负压沉贯过程中，吸力锚内部和外部邻近区域土体内的孔隙水在水头差作用下，产生渗流场。由于渗流的作用，土体强度可能发生变化，研究吸力沉贯过程中的渗流现象具有重要意义。通过将有限元分析结果与其他学者的试验结果进行对比分析，指出负压安装过程中影响吸力锚内部水力梯度的因素，并分析了渗流对于土体性质的影响规律。

Using suction for installation is the main character of suction anchor.It is important to consider the affection of suction operation on the bearing capacity of the installed anchor.The difference of water head causes the pore water to flow in the void of the soil.The seepage can de-grade the strength of the soil.So it is important to work on the seepage phenomenon.The FEM is used to analyze the distribution of pore pressure and seepage field in the soil.It is showed that the highest seepage velocity is at the tip of the anchor and can reduce the end resistance during instal-lation.The soil in the anchor is loosen by the upward seepage and cause the reduction of installa-tion resistance.
