Abstract
Tunnel diversion is a method of diverting upstream water through a diversion tunnel where the river valley is narrow and not conducive to the placement of an open channel, and where the geological conditions of the riverbank hills are favourable for the excavation of a tunnel. The construction of a tunnel diversion is limited by topographical conditions, construction budget, and construction scale. Therefore, the choice of a reasonable solution for the construction of a tunnel diversion has a certain influence on the cost, efficiency, and risk of construction A comprehensive consideration of how to construct a tunnel diversion can achieve a multi-objective optimization to reduce costs and increase efficiency. This paper incorporates risk as a constraint, with the radius of the upper part of the tunnel half arch and the lower tunnel elevation as optimizable variables for optimization. Based on the analysis of actual hydropower project data, Matlab is used to derive the most optimizable solution considering different possible scenarios of water flow, and the obtained results, show that the comprehensive objectives of shorter construction time and lower cost can be effectively achieved by analyzing the variables under different scenarios where the risk is a constraint.
