在港口工程中,防波堤及护岸采用预制混凝土护面块体进行护面以确保稳定、耐久,是常见的。“六五”至“七五”期间,我国北方几大港口(石臼港、青岛港、烟台港、秦皇岛港、营口港鲅鱼圈港区、大连港)新建或扩建的防波堤及护岸工程采用了大量的预制护面块体,其中采用最多的是工字型块体与四脚空心方块。近年来,护面块体预制技术有较大的改进。本文主要阐述工字型块体及四脚空心方块 In the port works, it is common for breakwater and bank protection to use prefabricated concrete face blocks for face protection to ensure stability and durability. During the “Sixth Five-Year Plan” to the “Seventh Five-Year Plan” period, a large number of new or expanded breakwater and bank protection works have been adopted in several ports in northern China (Shijiugang, Qingdao Port, Yantai Port, Qinhuangdao Port, Yingkou Port, Bayuquan Port, Dalian Port) Prefabricated masonry block, which uses the most is the I-shaped block and four hollow square feet. In recent years, face block prefabricated technology has been greatly improved. This article mainly describes the I-shaped block and four-legged hollow square
