摘要
针对双体打桩船在海上打桩施工中的安全性问题,建立了打桩施工过程中风浪流作用下施工船及锚链的耦合系统数值分析模型,通过计算得到了频域及时域下船体的运动响应.根据对施工环境条件及打桩垂直度要求,计算了打桩船多种施工工况下的运动响应,并对双体打桩船施工安全性进行了评价.
In view of the safety problems of pile driving catamaran in pile driving at sea,an analysis model is built to simulate the behaviors of the coupled system between hull and mooring under the condition of wind,wave and current.The motion responses in both frequency and time domains are obtained.According to the requirements of environmental conditions and piling perpendicular degree in construction,the values of motion responses for the pile driving catamaran are calculated under many kinds of working conditions,and the construction safety of the pile driving catamaran is evaluated.
