一、概述工字型块体(即北洛斯块体)以其抗浪能力强、消浪效果好和施工方便的优点,在我国防波堤工程中被广泛采用。从1970年起,至今已有16个防波堤工程采用两层工字型块体作护面层,并取得较好的效果。1986年4月～7月曾对这些工程作了一次调查:有一项码头兼防波堤工程的6吨方型工字型块,被台风冲击竖杆断头破坏严重;另一防波堤工程的堤头部分2.5吨工字型块护面层被台风冲击破坏(堤身的2.5吨工字型块完好);其他工程均完好,取得较好的防浪效果。征求各工程的施工意见,普遍反映安放工字型块的施

First, an overview I-block (that is, North Los block) with its anti-wave ability, good wave elimination effect and the advantages of construction convenience, in our breakwater project has been widely used. Since 1970, up to now, there have been 16 breakwater projects using two layers of I-shaped block as the surface protection layer and achieved good results. A survey of these projects was carried out from April to July 1986: there was a 6-ton square block of wharf and breakwater, severely damaged by a typhoon attack on the vertical stem, a dyke head part of another breakwater project The 2.5-ton I-block cover was damaged by the typhoon (the 2.5-ton block of the dike was in good condition); other works were completed and good anti-wave effect was achieved. Solicit the construction of the project views, generally reflect the placement of font block facilities
