研制消浪性能好、稳定性高、不易断裂、适于单层抛放、并且易于制造的新型混凝土护面块体,仍是当前发展和改进斜坡式防波堤的一项重要任务。法国于七十年代末研究成功的钩连块体(accropode),是在这方面值得注意的新成果。钩连块体在平面上的形状似两个锤头,形成四个短粗的突出物。在块体的中部,垂直于此平面上下另有两个短粗的突出物(图1)。自从《水运工程快报》1984 It is still an important task to develop and improve sloped breakwater at present to develop a new type of concrete retaining block which has the advantages of good wave-making performance, high stability and not easy to be broken, suitable for single-layer disposal and easy to manufacture. The successful accropode of France in the late seventies is a noteworthy new achievement in this respect. Hook block in the shape of the plane like two hammerhead, forming four short protrusions. In the middle of the block, there are two other short protrusions above and below this plane (Figure 1). Since the “Water Transport Express” 1984
