Abstract

The invention relates to the technical field of hydraulic tunnel reinforced concrete lining structure design, and discloses a high-pressure tunnel permeable lining structure optimization design method and system. The method comprises the following steps: firstly, determining a two-dimensional grid generation mode; establishing a mesh model for finite element calculation of the permeable lining based on the generation mode; constructing a permeable lining calculation model based on the grid model, and calculating influence parameters and target parameters of structural safety indexes based on the permeable lining calculation model; establishing a permeable lining structure economic performance equation based on the actual economic influence factors; and constructing a permeable lining optimization design equation set based on the influence parameters, the target parameters and the permeable lining structure economic performance equation, and solving to obtain an optimization design scheme. In this way, the influence of multiple factors is considered, and rapid and accurate optimization design of the high-pressure water-permeable lining structure can be achieved.
