摘　　要：水闸结构的安全是发挥其功能和效益的前提条件,而水闸的变形行为与水闸的安全运行密切相关。选取某一水闸实际工程为分析对象,确定水闸安全评价指标及其影响因素;建立合适的水闸安全分析有限元模型;基于正交实验法对各个影响因素的进行敏感性分析,采用极差分析法确定因素对安全评价指标的影响程度。实例分析结果表明:水闸底板与地基之间的接触属性对水闸最大水平位移的影响程度最大;地基土的材料物理属性对水闸最大竖向位移的影响程度最大。The safety of water gate structure is a prerequisite for its function and efficiency,and the deformation behavior of the water gate is closely related to its safe operation.This paper selects an actual water gate project as the analysis object,determining the safety evaluation indicators and their influencing factors of the water gate.Establish a suitable finite element model for safety analysis of water gates.Based on the orthogonal experimental method,sensitivity analysis was conducted on various influencing factors,and the range analysis method was used to determine the degree of influence of factors on safety evaluation indicators.The results of the case analysis show that the contact property between the bottom plate of the sluice and the foundation has the greatest impact on the maximum horizontal displacement of the sluice;The physical properties of the foundation soil have the greatest impact on the maximum vertical displacement of the sluice.
