采用流明弗染制示蹝沙,用以研究沙质海岸泥沙运动是很有效的,在国内外,已经成为研究沙质海岸泥沙运动及其对海岸工设施影响的一个新的重要方法。本文仅涉及一些具体方法的问题,叙述了染制流明沙的一般配方和工序,投放前的准备工作和资料的搜集,介绍了野外工作方法和所需的各种器材,讨论了资料的整理和分析中的有关问题,着重介绍了两种定量确定泥沙运移量的方法:“不变浓度法”及“完全计算法”。最后论述流明弗染色法的优缺点及几点需要继续改进的地方。
It is very effective to study the sediment movement of the sandy coast by using lumens, and it has become a new important method at home and abroad to study the sediment movement on the sandy coast and its impact on the coastal engineering facilities. This article deals only with some specific methods. It narrates the general formula and process of dyeing lumensa, preparations before launch and collection of data, introduces field work methods and various kinds of equipment required, discusses data collation and In the analysis, we mainly introduce two methods to quantitatively determine sediment transport: “invariant concentration method” and “complete calculation method”. Finally, the advantages and disadvantages of the lumens method and some need to continue to improve the place.
