Abstract:
Based on the definition of comprehensive utilization of the dredged material, through comparison and analysis of the comprehensive utilization of the dredged material at home and abroad, the present situation and the main problems in China are summarized. The corresponding countermeasures have been proposed. The present situation and the main features of the comprehensive utilization of the dredged material in China are: dredging amount is huge, utilization rate is generally low, the utilization purpose and the utilization methods are primitive, coordination among the departments concerned is not well organized, and special technical standards and policies have not been established. In order to improve the comprehensive utilization of the dredged material in China, countermeasures are proposed: publicity of the value of the dredged material should be increased; the dredged soil coordination management mechanism should be established; the dredged soil resources information sharing platform should be set up; in the corresponding laws and regulations, the relevant support for the comprehensive utilization of the dredged soil should be specified; the dredged soil utilization guide suitable for the situation in China should be compiled; the planning and scientific research of the comprehensive utilization of the dredged soil should be strengthend; and the demonstration project of the comprehensive utilization of the dredged soil should be conducted.
