【摘要】 １９９２年１０月在“珠江口航道整治规划”研究中应用中子活化示踪沙技术对矾石浅滩抛泥区泥沙的运动规律及其对航道的回淤影响进行了现场测验，就该抛泥区的合理性进行了分析。该抛泥区所抛泥沙主要沿矾石浅滩南移沉积，另有一部分西行进入伶仃航道，为减少航道的淤积，该抛泥区应适当向东迁移。更多还原

【Abstract】 In the study of dredge waterways plan in the Zhujiang River mouth,the spot observation was made in October,1992 by using the neutron activation tracer sediment technique to study the movement law of sediment bedload in the spoil ground in Fanshi shoal and its influence on siltation of water ways and analysis was made of the rationality of this spoil ground.The spoilt sediment in the spoil ground mainly moves southward and deposits along Fanshi shoal. Another part moves westward into Lingding channel.To decrease the siltation of waterways,this spoil ground should be appropriately moved eastward.更多还原
