珊瑚砂岛礁新吹填陆域钢板桩护岸工程监测分析

Monitoring Analysis of Steel Sheet Pile of Coral Sand Islands

基于珊瑚砂岛礁新吹填陆域钢板桩护岸施工过程中的沉降、位移、应变和应力监测数据,分析钢板桩变形和受力演变规律。利用ABAQUS软件"南水双屈服面模型"对钢板桩与珊瑚砂相互作用进行有限元分析,并将结果和工程监测值进行对比,二者一致性较强,揭示珊瑚砂条件下桩-土相互作用规律。

Based on the monitoring data of settlement, displacement, strain and stress during the construction of the steel sheet pile under the condition of coral sand foundation in the Indian Ocean island,the deformation and stress evolution of the steel sheet pile are analyzed. Using the ABAQUS integrated with the 'NHRI double yield face model',the interaction of sheet pile and coral sand is also analyzed by finite element method( FEM),and the results are compared with the engineering monitoring values. It shows a great consistency,revealing the pile-soil interaction law under coral sand conditions.
