Abstract

The invention discloses a three-dimensional modeling method for a branch section of an affiliated cavern of a pumped storage power station, and relates to the technical field of water conservancy and hydropower engineering structures. The method comprises the steps that basic parameters of the branch section are defined and obtained; constructing a three-dimensional model of the intersection section according to the basic parameters; the construction process comprises the following steps: acquiring a main tunnel line, a branch tunnel line and a position crossing relation thereof; setting a corner form of the intersection section and corresponding parameters; and creating a three-dimensional model of the intersection section according to the corner form. According to the method, the three-dimensional model of the branch section of the affiliated cavern of the pumped storage power station is quickly and accurately created through the cross section parameters and the position cross relation between the main cavern and the branch cavern, and compared with a traditional two-dimensional modeling method or a simple three-dimensional modeling method, the method can quickly generate the accurate three-dimensional model, the modeling efficiency is remarkably improved, and the modeling period is shortened.
