摘　　要：试验研究了砂水比、海水氯离子含量、海砂含水率及颗粒粒径等因素对海砂中氯离子含量的影响.结果表明:海砂中氯离子含量分别与海水氯离子含量及海砂含水率显著线性相关;堆积状态下的海砂,其含水率沿堆积高度呈递减规律,含水率稳定值对应的临界高度约为40cm;海水氯离子含量、海砂含水率及颗粒粒径等因素对海砂氯离子含量的影响规律均可用相应的数学关系来表征.Influence of sand-water ratio,chloride content in sea water,water content and particle size of dredged marine sand（DMS）on chloride content of DMS was studied experimentally.The results show that the chloride content of DMS is linearly associated with the chloride content in sea water as well as the water content of DMS.The water content of the accumulated DMS reduces with the pile height until it reaches a height of 40 cm.Moreover,the relationship between the multifactors（chloride content in sea water,water content and particle size of DMS）and the chloride content in DMS can be expressed as mathematical functions.
