摘要
通过物理模型试验,探讨了在波浪条件下,系泊单驳船横荡运动对沉管管段横荡运动的影响。研究结果发现考虑驳船横荡运动后的沉管横荡运动与忽略驳船运动的沉管横荡运动相比,两者存在明显不同。比较了考虑单驳船横荡运动后的沉管横荡运动与单驳船横荡运动之间的相关性,并探讨了不同波浪周期,波高和沉管沉放深度情形下沉管和单驳船横荡运动特性。
Physical model experiment is used to investigate single barge effect on tunnel element in the sway direction under waves. The results show that it is obviously different for tunnel element motions in the sway direction between without and with barge. It is compared with correlativity between sway motions of the barge and tunnel element with single barge. At last, sway motion characteristics of the barge and tunnel element with single barge under dif- ferent amplitudes, periods and immersed depths are analyzed.
