关于工字型块体的文献,最早发表于1966年9月在日本东京召开的第10届海岸工程会议的论文集。实际上,早在1964年东伦墩港就开始使用约2000个重达17.9吨的工字型块体,取代遭到局部损坏的36.3吨的混凝土方块。后来仅仅由于局部地基掏空,形成一个陡峭的沉陷坑,才造成大约10多个工字块体破损。 The earliest published literature on the I-shaped blocks was first published in the Proceedings of the 10th Coastal Engineering Conference held in Tokyo, Japan in September 1966. In fact, as early as 1964, about 2,600 I-shaped blocks weighing 17.9 tons were used in Donglundun Port, replacing 36.3 tons of concrete blocks damaged locally. Later, just because of partial foundation emptiness, the formation of a steep subsidence pit, it caused about more than 10 I-block body damage.
