水工模型试验是水运工程设计的重要工具和有效辅助手段。通过模型试验可以获得设计的重要依据,选择最佳工程方案,避免浪费,节省投资。 模型试验的比尺主要取决于试验问题的性质、模型范围、试验精度、原体状况和可供使用的试验场地设备等。为增进相似性,减低比尺影响,提高试验精度及适应河工、港工与海岸工程的建设规模日趋庞大、涉及范围广阔的情况,近年来国外大都趋向采用大比尺、大模型。但为了节省经费和时间以及由于试验场地的限制,在某种特定的要求
Hydraulic model test is an important tool for waterway project design and an effective aid. Through the model test can get an important basis for the design, select the best project to avoid waste and save investment. The scale of the model test mainly depends on the nature of the test problem, the model range, test accuracy, the status of the original body and the available test site equipment. In order to promote similarity, reduce the influence of scale, improve test accuracy and adapt to river works, the construction scale of port engineering and coastal engineering is increasingly huge and covers a wide range of situations. In recent years, most overseas countries tend to adopt large scale and large models. However, in order to save money and time and due to the limitations of the test site, in a particular request
