【提要】 PCC樁在圍堤結構中的應用可以采用單排聯(lián)體結構和雙排框架結構兩種型式，其中雙排框架結構形式可與連接插板共同使用。設計中要考慮單樁施工階段和樁體正常使用階段的穩(wěn)定問題，當整體抗傾覆不滿足要求時，可采用增加樁長和其他一些措施。
【關鍵詞】 PCC樁結構圍堤 單樁 雙排樁 穩(wěn)定
Application of PCC Enclosing Structure in Seafilled Engineering/Gong Dikuai,Xia Tangdai(Geotechnical Engineering Institute,Zhejiang University,Hangzhou 310027,China)Abstract:Two kinds of structures which are jointed structure of singlerow piles and frame structure of doublerow piles,can be adopted in the seafilled PCC enclosing engineering.The flashboard can be used simultaneously in the latter.In design,the stability of the system should be taken into account in the construction stage of single pile and the normal use stage,and adding the length of the pile and some other methods can be adopted to meet the integral overturn requirement.
Keywords:PCC enclosing structure; single pile; doublerow piles；stability
