Selection of Sluice Bottom Slab Structures Based on the AHP-TOPSIS Method
ZHANG Li
Abstract：The sluice bottom slab is a crucial foundation of the gate chamber structure,and the appropriate slab type is essential for ensuring the safe operation of the gate chamber.An evaluation system for selecting sluice bottom slab types was constructed in this study,with criteria such as structural stability and cost-effectiveness.The AHP-TOPSIS combined model was used to comprehensively compare different structural types of sluice bottom slabs.Taking the demolition and reconstruction project of a regulating gate in Hezheng County as the case study,the results showed that the evaluation score for the reinforced concrete solid structure was significantly higher than that for the reinforced concrete hollow box structure.The findings provide the important bases for selecting sluice bottom slab structures.
