摘　　要：耙吸式挖泥船在硬黏土底质施工中,存在堵耙、闷耙等问题,生产效率较低。介绍天航局耙吸挖泥船在鲅鱼圈港25万吨级航道施工开挖硬黏土时,成功研制犁齿、软格栅的施工方法,有效解决堵耙、闷耙等问题,综合生产能力提高60%以上。When dredging hard clay by the trailing suction hopper dredger, there has some problems such as draghead blockage, cavitation and low production. This paper mainly introduces the dredging construction method for the stiff clay Bayuquan port 250 000 t channel by the trailing suction hopper dredger with plough teeth and soft grid, which effectively solves the problems of draghead blockage and cavitation, and raise the comprehensive production capacity by more than 60%.
