摘要
为探明不同波态时双排钢板桩围堰的不同响应,采用光纤测试技术,通过水槽试验对比研究立波和近破波对双排钢板桩围堰产生的波浪荷载作用机理。结果表明:立波对双排钢板桩围堰的主要不利作用是反射波导致的海侧钢板桩踢脚冲刷;近破波对双排钢板桩围堰的主要不利作用是巨大的破碎能量和快速冲击导致钢板桩变形,可能造成钢板桩接头错位、渗漏、冲刷等事故。
To explore the response of a double-row steel sheet pile cofferdam under the condition of different wave modes, the effects of near breaking wave and standing wave on steel sheet piles was compared through flume test using optical fiber testing technology, and the mechanism of wave load caused by standing wave and near breaking wave was analyzed. It is found that the main unfavorable effect of standing waves on the double-row steel sheet pile cofferdam is the scouring of the seaside steel sheet piles caused by the reflected waves. The main unfavorable effect of the breaking wave on the double-row steel sheet pile cofferdam is the huge crushing energy and rapid impact during wave breaking. The deformation of the steel sheet pile may cause accidents such as leakage of the joint and soil erosion of the infilled sands.
