A weighted logarithmic ideal point particle swarm optimization(WLIPPSO)method was designed. Cramer’s rule was utilized to handle constraints for towing forces and angles of towing forces. The simulation was carried out through tube floating control example of immersed tube tunnel in island tunnel project of Hong Kong-Zhuhai-Macao Bridge. Simulation result shows that when the total number of tugboats is six, in rising tide the floating speed is 4.770 kn, the fitness is 0.720, the number of working tugboats is three, and the surplus capacity product of towing force is 2.693×1020 kN6. In falling tide the floating speed is 1.750 kn, the fitness is 3.042, the number of working tugboats is five, and the surplus capacity product of towing force is 3.352×1019 kN6. So the model and method proposed have strong applicability, the fitness is better, the number of working tugboats is smaller, surplus capacity of towing force and floating speed are higher. 8 tabs, 5 figs, 24 refs %K 沉管平移控制 %K 拖轮合力 %K 合力矩 %K 粒子群优化 %K 加权对数理想点法< %K br> %K translation control of immersed tube %K resultant force of tugboats %K resultant moment %K particle swarm optimization %K weighted logarithmic ideal point method %U http://transport.chd.edu.cn/oa/DArticle.aspx?type=view&id=201602004
