【摘要】 为满足电建海装001号打桩船近海作业需求，使用基于三维势流理论与边界元法的工程软件ANSYS-AQWA,对打桩船在不同海况下的环境载荷进行计算。对水动力计算结果进行传递，使用有限元方法采用隐式动力学求解，对在不同环境载荷下桩土耦合运动中定位桩的运动进行校核，并对风速和波浪周期两个参数进行敏感性分析。结果显示，打桩船在大多数海况下作业存在安全余量，定位桩的运动与波浪周期和风级密切相关。更多还原

【Abstract】 In order to meet the offshore operation requirements of pile-driving vessel No. 001, the environmental loads of the vessel under different sea conditions were calculated by using the engineering software ANSYS-AQWA based on the three-dimensional potential flow theory and boundary element method. The results of hydrodynamic calculations were transferred to the finite element method using implicit dynamics solution to calibrate the dynamic response of positioning piles in soil-pile interaction motion under different environmental loads, and the sensitivity analysis was carried out for two parameters, namely, wind speed and wave period. The results showed that there is a safety margin for pile-driving vessel to operate in most sea conditions, and the motion of the positioning load is closely related to the wave period and wind level.更多还原
