- •
We establish a failure mechanism of the cavern roof with anchor cable in water-rich stratum.
- •
A design method of anchor cable is obtained based on the upper-bound theory and Hoek–Brown criterion.
- •
We discussed the factors that affect the design parameters and corresponding recommendations.
- •
The design method is applied to determine the anchor cable parameter of a pump station.
