| 摘 要： | 对某已建水库围堤基础液化段，采用FLAC 3D软件进行了数值模拟研究，对高压旋喷墙加固效果进行了分析评价，论证了高压旋喷墙加固方案的合理性和可靠性。分析结果表明，围堤基础部分土层有液化趋势，土体会产生较大的侧向变形，进行围堤基础加固很有必要。高压旋喷墙很适合对该水库进行除险加固，加固后的围堤基础液化段的应力和变形都在允许范围之内，能够保证水库的安全运行，这为已建水利工程的维修加固提供了技术依据。

| Abstract: | The liquefied embankment foundation of a reservoir is simulated by using FLAC 3D software; the reinforcing effect of the high pressure circular jet grouting diaphragm wall is estimated; the reliability and reasonableness of the reinforcing scheme through high pressure circular jet grouting diaphragm wall are verified. From the analysis there is trend of liquefaction in the embankment foundation, and lateral deformation will occur in soil; therefore it is necessary to reinforce the embankment foundation. The high pressure circular jet grouting diaphragm wall is suitable for reinforcing the constructed reservoir, safety of the reservoir can also be guaranteed because stress and deformation of the liquefied embankment foundation are in the permittable limit. Technical information can be provided for maintaining and reinforcing the constructed hydraulic projects. |
