泥沙动力学研究方法、技术、进展及沉积学意义

Abstract

分析水沙运动规律是沉积动力学与泥沙动力学面对的共同课题。泥沙动力学研究为解决江河治理和水利工程建设中的泥沙问题提供了重要思路和手段。本文介绍了泥沙动力学的研究方法、试验技术和研究进展。从沉积动力学角度借鉴泥沙动力学领域的研究方法、试验技术和理论成果，从动态观点研究沉积动力过程中各种变量与条件之间的定量关系进而研究沉积物搬运和沉积的动力机制，建立和完善受水动力约束的沉积环境标志，将拓展沉积动力学研究的理论视野和思路，提高沉积环境研究的精度，推动沉积模式的建立和学科概念的形成，丰富沉积动力学的内涵。 Analyzing the motion law of water and sediment is common topic of sedimentary dynamics and sediment dynamics. Research of sediment dynamics can provide an important way for solving se-diment problem such as river regulation and water conservancy project construction. This paper introduces the approach of sediment dynamics study, testing technology and research progress, using research methods of sediment dynamics, experimental technology and theoretical results from the perspective of sedimentary dynamics, researching on quantitative relationship between various variables and conditions of sedimentary dynamic process from dynamic view, and then studying the dynamics mechanism of sediment transport and deposition, establishing and im-proving depositional environment mark under the constraint of hydrodynamic, which will expand theory field and thoughts of sedimentary dynamics research, and improve precision of sedimentary environment study, promote the establishment of depositional model and formation of discipline concept, and enrich the connotation of sedimentary dynamics.
