| 以温州框架式海堤为背景,采用有限元强度折减法,分析密排桩结构参数和桩基周围淘蚀对框架式海堤变形、稳定性的影响。计算结果表明：随着密排桩桩长增加,密排桩桩身水平位移不断减小；密排桩径对桩身水平位移的影响较小；密排桩排间距对桩身水平位移基本没有影响；随着桩基周围淘蚀深度增加,密排桩桩身水平位移不断增大,增大幅度最大位置都发生在桩顶；随着密排桩桩长增加,框架式海堤整体稳定安全系数增大；随着密排桩桩径增大,框架式海堤整体稳定安全系数增大；密排桩排间距为2.1m时,框架式海堤整体稳定安全系数最小。 |

| Abstract: |
| Taking Wenzhou frame seawall as the background, the finite element strength reduction method is used to analyze the influence of the structural parameters of dense row piles and the erosion around the pile foundation on the deformation and stability of the frame seawall. The results show that with the increase of the length of dense row piles, the horizontal displacement of dense row piles decreases; the influence of the diameter of dense row piles on the horizontal displacement of piles is small; the spacing of dense row piles has little effect on the horizontal displacement of piles; and the horizontal displacement of dense row piles increases with the increase of erosion depth around piles. The maximum locations occur at the top of the pile. With the increase of the length of dense row piles, the overall stability safety factor of frame seawall increases; with the increase of the diameter of dense row piles, the overall stability safety factor of frame seawall increases; When the spacing of dense row piles is 2.1 m, the overall stability safety factor of frame seawall is the smallest. |
