摘要
为提升软土地基水闸不均匀沉降风险甄别质量,便于病害水闸除险加固处理,基于ABAQUS软件,建立了水闸不均匀沉降变形分析三维有限元数学模型,并形成了一套水闸不均匀沉降四级风险预警机制。以江苏苏北车轴河闸为例,应用所提方法分析其不均匀沉降风险,结果显示,部分工况可能导致水闸出现2~3级风险预警。研究成果可为类似工程提供参考。
Based on ABAQUS,this paper established a three-dimensional finite element mathematical model for settlement and deformation analysis of sluice on soft soil foundation,and formed a four-level early warning mechanism for uneven settlement and deformation of sluice.It is helpful for the sluice management unit to improve the ability to identify the risk for uneven settlement and deformation of sluice,and carry out the work of risk elimination and structure reinforcement.The application case of Chezhouhe Sluice shows that several working conditions may trigger the 2-3 level risk warning of the sluice.The research results can provide technical reference for similar sluice projects.
