Multi-objective Optimization of Long-distance Water Conveyance Pipe Diameter Considering Economy and Hydraulic Performance
摘要
Abstract
To address the challenge of coordinated optimization between economy and safety in the design of pipe diameters for long-distance water conveyance projects,this study takes the major Chuo-Liao Water Diversion Project as a research object and proposes a pipe diameter optimization method that integrates multi-objective decision-making with engineering constraints.By establishing an objective function system aimed at minimizing both the cost per unit pipe length and the pressure drop,the TOPSIS algorithm is introduced to evaluate and rank solution sets.The sensitivity of pipe diameter selection to variations in temperature,flow rate,and weight allocation is systematically analyzed,while constraints on flow velocity and pipe diameter from practical engineering are incorporated.The results demonstrate that the optimized pipe diameter scheme significantly reduces project investment while ensuring a design flow velocity of 1.2～1.6 m/s and an allowable pressure drop of 10～100 mm H₂O per 100 meters.This research provides a quantifiable method for the scientific selection of pipe diameters in long-distance water transmission systems,offering valuable insights for the detailed design of similar projects.关键词
