【提要】 PCC桩在围堤结构中的应用可以采用单排联体结构和双排框架结构两种型式，其中双排框架结构形式可与连接插板共同使用。设计中要考虑单桩施工阶段和桩体正常使用阶段的稳定问题，当整体抗倾覆不满足要求时，可采用增加桩长和其他一些措施。

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.
