Intelligent calculation method for transient boundary load of tunnel water disaster

Abstract

The application discloses a kind of tunnel water disaster transient boundary load intelligent calculation method, belong to tunnel engineering technical field, including the following steps: obtaining the geometric information of tunnel calculation section, and the section is meshed in tunnel longitudinal direction, obtain the geometric data of each discrete cross section;Based on the geometric data, determine the water storage characteristics of the tunnel calculation section to divide the water storage stage, and construct the mapping relationship dataset between the water storage area of each cross section and the water level height of tunnel center axis;Based on the law of conservation of mass, combined with the characteristics of current water storage stage and the mapping relationship dataset, calculate the transient water level distribution data of water propagation along the tunnel longitudinal direction;By reducing the three-dimensional water storage problem to two-dimensional longitudinal section problem, combined with tunnel gradient and drainage information to divide water storage stage, and based on the law of conservation of mass to construct water quantity balance equation of each stage.
