摘要：“块石护面"结构在海堤工程的坡面防护中应用广泛.浙江省沿海海堤工程由于波浪环境的恶劣性，在台风经常使沿海海堤“大块石护面”受损.同时“块石护面”对块石尺寸大小要求较高，对一些石料缺乏或石料单重无法满足设计要求的地区来说，通过先理砌大块石后进行混凝土灌缝较宜.据此以温州瓯飞围坚工程为例，对理瑚灌缝的施工工艺、操作要点、质量保证措施等方面进行了阐述分析，证并通过工效证明大块石理砌灌缝在浙江沿海可以应用。

( Dongzhou Branch Office of Zhejiang Design Institute of Water Conservancy and Hydro Power , Hangzhou 310002, China Abstract : As the most ecological and common slope protection structure in the sea dike engineering , the " armor stone" in the sea dike engineering in Zhejiang Province was damaged almost every year in the typhoon period due to the bad wave en vironment. At the same time, the application of “armor stone" asks for big stones, some places with less stones or unquali -fied stones can not meet the requirements of engineering design . Therefore, stone grouting concrete is a good solution for concrete masonry block stone. Based on the case of Oufei Reclamation Project in Wenzhou , the constructing technology, operating points and quality assurance measures are also discussed and summarized in this article . It proves that large stone
masonry pouring can be used suceessfully and is worthy promotion in the coastal areas of Zhejiang . Key words; sea dike; armor stone ;repressive layer; stone grouting concrete
0引言
在近年来的围垦工程施工中，海堤通常采用复式断面土石混合堤，迎潮面坝体和内侧子堤采用抛石填筑，中间填筑闭气土方防渗.迎水面镇压层护面结构通常是块石理砌或灌砌石护面，对块石尺寸大小要求较严格，且海堤迎水面镇压层护面结构施工受潮水影响较大，施工工期短.本文结合浙江沿海某围垦工程实际，介绍一种大块石理砌和灌础石

温州瓯飞围垦工程海堤镇压层大块石理砌护面厚度为80cm，根据近几年浙江沿海围垦工程的经验，大块石理砌护面抗风浪冲击机理较为复杂，无论从理论还是波浪模型试验的结果与实际抗风浪冲刷能力不甚对应，而施工现场附近的大块石单重难以满足设计要求，需对海堤镇压层护面抗冲刷能力不足的部位进行混凝土灌缝补强.所灌混凝土自块石底面往上60cm，C20细石混凝土经振捣密
