摘　　要：人工岛在景观河道或自然湿地公园项目整治中通常作为景观节点来打造和应用。其多利用河道、池塘清淤土或工程中多余未利用土堆填而成,往往因无法采用机械压实及长期受水流冲刷浸泡而发生坍塌。本文结合南京市珠西河综合改扩建工程实际,提出了预制空心管桩与木桩组合式护岸形式,有效解决了人工堆岛岸坡易失稳及坡脚防冲刷问题,且施工简单、工期短、造价适中,经稳定复核符合规范要求,可为其他类似工程提供参考。Artificial islands are usually built as landscape nodes in the renovation of landscape river or natural wetland park projects,and are often made of dredging soil in rivers and ponds or excess unused soil filling in engineering.It often collapses because it is unable to be compacted by mechanical compaction and is washed and soaked by water for a long time.Based on the practice of the comprehensive reconstruction and expansion project of Zhuxi River in Nanjing,this paper puts forward the combined revetment form of precast hollow pipe pile and wood pile,which effectively solves the problems of easy instability of artificial island bank slope and anti-erosion of slope foot,and has the advantages of simple construction,short construction period and moderate cost,hich meets the requirements of the code after stable review and provide reference for other similar projects.
