摘　　要：针对横琴岛天沐河直立护岸段下卧深厚软土且陆域施工条件受限的情况,选择双排咬合灌注桩+格构式水泥搅拌桩基础、悬臂板桩+格构式水泥搅拌桩基础、扶壁结构+灌注桩基础3个直立式护岸结构方案,分别从结构安全、施工难易程度及工期、与周边工程衔接性、经济性等方面进行比较,推荐采用双排咬合灌注桩结构形式。工程实践结果表明:双排咬合灌注桩结构能较好地适应有限的施工场地和深厚的软土地基,工期较短且造价经济,可为类似河道整治工程提供参考。In consideration of the limited construction area and thick soft silty soil,three structural schemes,i.e.,double-row interlocking piles with cement mixing piles,cantilever sheet pile with cement mixing piles,buttress structure with bored piles,are compared from the structure safety,construction difficulty,construction period,surrounding projects coordination and economic efficiency.The results show that the double-row pile structure is the best due to its adaptability to the limited construction site and thick soft silty soil,and thus may provide reference for similar river regulation projects.
