摘　　要：针对耙吸船在浚挖水深较小、疏浚量较大、运距较远的航道作业时常常要浪费大量时间候潮的问题,开发基于MATLAB的耙吸船减载或候潮施工方案优化软件。该软件根据施工海域潮汐情况,预测耙吸船在候潮施工和减载施工2种工况下的生产率,从中选择更为高效的施工方案。同时,该软件可以精准计算挖泥时间,为施工人员提供更为合理的参考,在保障耙吸船安全施工的同时提高船舶施工效率。研究成果成功应用于马来西亚槟城吹填造地工程中,使施工周期缩短10%,生产率提高7%。Trailing suction hopper dredgers(TSHD)always waste a lot of time to wait for tide when dredging channels with shallow water, large dredging volume, and longer hauling distance, thus we develop the construction scheme optimization software based on MATLAB for the TSHD. It can predict the efficiency of the TSHD under working conditions of waiting tide and relieving load according to the tidal situation of the construction sea area and choose a more efficient construction scheme. Furthermore, it can calculate the excavation time and thus provide more reasonable references for the construction personnel. It can not only ensure safe construction but also promote the construction efficiency of the TSHD. The research result has been successfully applied to the land reclamation works of Penang City, Malaysia, with the construction period shortened by10% and productivity increased by 7%.
