摘　　要：以作业的自升式风电安装船(简称风装船)为研究对象,建立力学模型并采用正交法对其因子进行试验设计,研究其工程力学参数并进行优化。研究结果表明,作业水深为重要因子,作业风向角为较重要因子,得到优化参数为:风向角为0°,入泥深度为4 m(硬质土)及9 m(软质土),气隙为10 m,桩腿横向长度为70 m。优化后风装船随时间变化的船位置点位移幅值及弱点轴向应力幅值减少,改善了力学特性。A mechanical analysis model was established and the orthogonal design was adopted to study engineering mechanics of self-elevating turbine installation vessel （TIV）. Results showed that water depth is the most important factor and angle between wind and TIV is the important factor. Optimized parameters are as followings ： wind angle is 0 degree ; driving depths are 4 m （hard soil） and 9 m （soft soil） ; air gap is 10 m and horizontal length of legs is 70 m. A better result of engineering mechanics of TIV will be gained by adopting the optimized parameters, because displacement amplitudes of vessel point and axial stress amplitudes of weaknesses points which change over time are reduced. A referential value for processes of designing, building and operating of TIV are provided
