研究海岸带的泥砂运动不仅有重要的理论意义,而且对海港的港址选择、港口及航道的疏浚、各种水工建筑物的稳定性、护岸工程的建造等都有重要的实际意义。 对泥砂运移规律的研究,目前常采用的方法有水文气象要素统计法、地貌形态分析法、矿物岩石分析法、人工示踪砂法和地球化学法等。根据工作的性质和要求,采用上述一种或几种方法,以获得可靠的结果。上述这些方法各有优点,但矿物岩石分析法的优点较多。首先,具有普遍意义的是在任何地区都可以运
Studying the sand movement of the coastal zone not only has important theoretical significance, but also has important practical significance for harbor selection, dredging of ports and navigation channels, stability of various hydraulic structures and construction of revetment. The research on the law of sediment transport often uses hydrological and meteorological elements statistics, topographic analysis, mineral rock analysis, artificial sand tracing and geochemical methods. Depending on the nature and requirements of the job, one or more of the above may be used to obtain reliable results. Each of these methods has advantages, but there are many advantages of the mineral rock analysis method. First of all, it is of universal significance that it can be transported in any area
