南科院海岸河口围垦技术考察组一行三人,于1984年5月13日至6月12日,对加拿大国家科学研究院等八个单位进行了有关海岸河口室内试验技术的考察。加拿大是一个科技比较发达的国家,在我们所要考察的几个方面,有很多东西值得我们学习和借鉴,其中主要有:一、海堤或防波堤人工护面块体的强度模拟。过去,波浪作用下人工护面块体稳定试验,一般均按重力相似模拟块体的几何尺寸及重量,稳定性用失稳率表示。加拿大的新方法是选用石膏等材料制作护面块体,不仅模拟其几何尺寸及重量,还模拟块体的强度。通过对几个港的防波堤
South Coast Institute of Coastal Estuary reclamation technology inspection team of three people, from May 13, 1984 to June 12, on the Canadian National Academy of Sciences and other eight units on the estuary of the indoor test technology inspection. Canada is a country with comparatively developed science and technology. There are many things we should study and learn from the aspects that we should study. Among them, there are mainly: 1. Intensity simulation of seawall or breakwater artificial face block. In the past, the stability test of the artificial face block under the wave action generally simulated the geometric size and weight of the block by gravity and the stability was expressed by the instability rate. The new method in Canada is to use gypsum and other materials to make face block, not only to simulate the geometric size and weight, but also to simulate the strength of the block. Breakwater through several ports
