摘　　要：以深中通道工程海底隧道为依托,对管节在港内系泊防台开展物理模型试验,量测系缆力以及管节运动响应参数,探究管节在系泊状态下的动力响应特征及规律。研究主要结论有:环抱式港区内泊位系泊条件是对波浪掩护条件最好的位置最优,靠近口门的泊位最差;不同载况下,空载时风场的作用最显著而有沉放驳和测量塔的重载+工况下,风的作用力也要明显大于仅管节的重载情况,与管节半载时接近(重载+沉放驳+测量塔>重载);E32非标准管节系于突堤码头(GC1泊位)时,在各载况条件下,半载时的缆力相对最大,其中尼龙缆的最大张力为773 kN,钢缆的最大张力为1024 kN,不同载况下缆力大小的排序为半载>重载+沉放驳+测量塔>重载。Based on the Shenzhen-Zhongshan Link project,physical model tests were conducted on the mooring of pipe joints in the harbor to prevent the platform,and the bollard force and the motion response parameters of pipe joints were measured to investigate the characteristics and laws of the dynamic response of pipe joints under mooring condition.The main conclusions of the study are:The mooring conditions of berths in the ringed harbor area are optimal for the location with the best wave cover conditions,and the worst for the berths near the mouth;Under different loading conditions,the effect of the wind field is the most significant at no load,while the wind force is also significantly greater under heavy load+working conditions with a sinking barge and measuring tower than the heavy load condition with only pipe section,which is close to the pipe section at half load(heavy load+sinking barge+measuring tower>heavy load);When E32 non-standard pipe section is tied to the jetty(GC1 berth),the cable force at half load is relatively the largest under each load condition,in which the maximum tension of nylon cable is 773 kN and the maximum tension of steel cable is 1024 kN,and the cable force under different load conditions is ranked as half load>heavy load+sinking barge+measuring tower>heavy load.
