详细介绍
20世纪60年代末，以空心造型为主的人工护面块体开始独立发展起来，这里面四脚空心消浪块模具是典型代表之一。四脚空心块主要依靠块体与块体之间的摩擦力来保持相互稳定，同时为了保持其护面结构外观及整体稳定性，在设计过程中对预留的缝、高差等也有一定的要求。**初日本提出安防两层四脚空心块作为护面结构，国内进行单层与两层安防模型试验。试验表明，单层安装与两层安装的稳定性基本，只是单层与两层相比波浪爬高稍微有些大。之后，国家在防浪地区基本都使用单层安装，例如泰山核电站消浪护岸采用的是单层安装，并且取得了良好的防护效果。目前四脚空心块多采用单层摆放，使其具有孔隙率高、造价低的特点。At the end of 1960s, the hollow block of artificial face protection began to develop independently, in which the four foot hollow wave block mold is one of the typical representatives. The four foot hollow block mainly relies on the friction between the block and the block to maintain mutual stability. At the same time, in order to maintain the appearance and overall stability of its protective structure, there are certain requirements for the reserved joints, height differences, etc. in the design process. At first, Japan proposed two-layer four foot hollow block as the protective structure, and carried out single-layer and two-layer security model tests in China. The test shows that the stability of single-layer installation is basically the same as that of two-layer installation, but the wave run-up of single-layer installation is slightly higher than that of two-layer installation. After that, the country basically uses single-layer installation in the anti wave area, for example, the wave Bank of Taishan nuclear power station adopts single-layer installation, and has achieved good protective effect. At present, four foot hollow blocks are mostly placed in single layer, which makes them have the *acteristics of high porosity and low cost.
