To comprehensively and systematically analyze the advantages and disadvantages of various existing artificial armour units，the development of representative artificial armour units is introduced，and the stability principle of armour units is analyzed. The stability coefficient KD and stability number Ns of mainstream armour units are summarized and compared，which are used to evaluate the stability of blocks，and the amount of concrete per unit area and the number of blocks are introduced to evaluate their economy. On this basis，6 common artificial armour blocks are selected，and their stability and economy are quantitatively compared. Meanwhile，based on foreign standards and results in the cutting edge of armour units，suggestions on calculation and usage requirements of Chinesepode recommended in JTS 154—2018 Code of Design for Breakwaters and Revetments are proposed. Finally，it is concluded that the quantitative comparison results of the stability and economy of the commonly used artificial armour units can be used for reference by designers when comparing and selecting armour units. We put forward some suggestions for the use of the Chinesepode in the national standard，so that Chinese design enterprises can better connect with foreign customers.
