摘要
为了满足港珠澳大桥沉管安装的起、抛锚需要,研发建造新型多用途起锚艇。通过计算沉管的水流力,优化沉管安装布锚方案,对锚抓力进行试验,对沉管进行物模试验和对起锚设施进行分析,最终确定起锚艇的主要技术指标和设备配置。实船建造投产后使用表明,新造多用途起锚艇的各项性能指标优良,达到了预期的目标。
The function of the new multipurpose anchor boat is to meet the demands of anchor handing work in the process of immersed pipes installation in the project of Hong Kong-Zhuhai-Macao bridge.Through calculating the flow force of immersed pipes, optimizing the plans of immersed pipes installation and anchor, testing of anchor holding power, experimenting with im-mersed pipes physical models and analyzing of the anchor handing facilities, the main technical parameter indicators and device configurations of anchor boat are determined.The results after anchor boat putted into using show that all of the performance inde-xes are good to achieve the desired objectives.
