The application discloses a kind of three-dimensional positive design method for pumped storage
power station accessory cavern group, belong to the technical field of water conservancy and
hydropower engineering structure design and manufacture.It provides a kind of three-dimensional positive design method that can effectively solve the design difficulty of underground accessory cavern group, improve design quality and
design speed.The three-dimensional positive design method includes the following steps, first generate three-dimensional geological model and
contour line on
design software, then import
field survey data to generate three-dimensional geological model containing
terrain, then based on this, successively carry out hole axis plane line design, generate three-dimensional hole axis, generate three-dimensional
underground cavern group, draw points on axis, calculate cavern spacing, output the
distance matrix of each cavern, calculate the
minimum distance between each axis, and finally judge whether the distance meets the requirements.Further, the problem of effectively solving the design difficulty of underground accessory cavern group is solved, and the purpose of improving design quality is achieved.
