东平湖二级湖堤不同护坡消浪作用分析

Analysis on Function of Revetment and Subducting Waves in Secondary Dam of Dongpinghu Lake

东平湖二级湖堤石护坡在2001,2003年洪水中发生大面积损坏,急需加固。通过对护坡一般结构形式特点的分析,初步选定砌石护坡、混凝土喷护、四脚空心体、扭工字体4种加固形式,在此基础上,通过波浪爬高计算分析,从技术、经济两方面进一步对四种护坡形式进行分析,四脚空心体、扭工字体消浪效果好,投资省,综合考虑群众生产等因素,二级湖堤石护坡加固四脚空心体加固方案最适宜。

Secondary bank of Dongyinghu Lake was destroyed badly in 2001 and 2003. It should be reinforced immediately. Though analysis on statistics of common structure of revetment, 4 kinds of reinforcements are selected, such as rockfilling facing, concrete shotting, hollow teprapod and bolosse. On these basis, through analysis on wave height measurement, 4 kinds of revetment styles are analyzed. It is regarded that hollow teprapod and bolosse have good effect with low money, and hollow teprapod is the most suituable method in secondary dam revetment.
