洪泽湖航标防撞设施设计

根据洪泽湖南线3级航道最不利船型和碰撞分析,按现有单柱式航标桩基设计抗撞能力110t,设计了2种结构形式的航标防撞设施,经实船撞击试验,取得现场实测数据。结果表明安装防护设施能有效吸收船舶撞击能量80%左右;通过有限元模型计算,推算出的船舶撞击力大于现有规范参考值20倍左右;采用钢漂护舷防撞设计方案最优,能有效地保护现有航标。

Anticollision Facility Design of Hongze Lake Navigation Mark

According to the south line of three paths Hongzehu the worst ship from and collision of Hongze Lake south line 3 grade channel,and anticollision capacity of single-pole navigation mark pile foundation,this paper designed two kinds of structure forms of anti-collision facilities with actual ship collision tests access to on-site measured data. Results show that the installation of protective facilities can effectively absorb 80% impact energy the ship impact force is greater than the reference value of existing norms about 20 times,the steel bull floating fender design is optimal,which effectively protect the existing aids to navigation.
