摘　　要：珠海横琴新区市政基础设施项目滨海堤防工程需满足100年一遇的防潮标准,堤顶规划高程为3.7m,轴线全长13.983km。堤型选用斜坡式结构,堤岸顶部断面型式推荐采用直立式堤顶坡面方案。现有堤防自身稳定储备不足,加固后的护岸断面其抗滑稳定性计算结果能够满足正常及非正常运行等条件下的最小安全系数要求。The coastal embanknnt engineering of tmnicipal infrastructure projects need to meet once in 100 years for the standard of raaisture-proofing in Hengqin new area of Zhuhai city. 3he progmmm~ elevation of the embank- raent top is 3.7m, and the axis length is 13.983km. The ramp structure is selected for the embankment type, and the vertical slope scheme is reconm^nded to be utilized for the section pattern of embankment top. The stability of existing embankment is poor. Accroding to the stability calculation of reinforced embankment section, the demand of mininrun safety factor for the normal and abnormal nmning condition of the embankment could be satisfied.
