Analysis of Leakage Causes in Hydraulic Structures Based on DEMATEL-ISM

To solve the problem of leakage in the operation process of hydraulic structures, this paper conducts a cause-effect analysis based on the DEMATEL-ISM method. Firstly, a factor system causing leakage in hydraulic structures is established through literature analysis and expert interview methods. Then, the laboratory decision-making analysis method (DEMATEL) is used to construct a matrix to analyze the influence and importance of the causal factors of hydraulic structure leakage. The centrality index is used to rank the importance of the causal factors. Finally, the interpretive structural model (ISM) is used to hierarchically divide the causal factors, analyze the coupling and interaction between them, and propose targeted suggestions. This paper deeply analyzes the main causes of leakage in hydraulic structures and comprehensively explores the control methods of leakage problems, providing a reference for preventing leakage problems in the design and construction stages of subsequent hydraulic structures.
