| 摘 要： | 通过离心试验对箱筒型基础防波堤在水平静荷载下的位移特性进行了研究.研究表明:防波堤发生向港侧转动,海侧和港侧分别发生向上和向下位移,整个防波堤发生向港侧水平位移.地基土体强度越大,转角、港侧竖向位移量和水平位移量越小,而海侧竖向位移量越大.荷载比大于屈服荷载比后,位移速率显著增大,地基土体强度越高,屈服荷载比越大. |

| Abstract: | Displacement characteristics of bucket foundation breakwater under horizontal static load are studied through centrifuge model test. Test results show that： breakwater tilts to harbor side, sea side and harbor side will move upward and downward respectively. Tilt angle, harbor side vertical and horizontal displacements decrease with foundation soil strength, while sea side vertical displacement increases, with the larger soil strength. When load ratio is larger than yield load ratio, displacement velocity increases significantly. The yield load ratio increases with the larger foundation soil strength. |
