Rock-mass parameters are very important to underground cavern design and construction; many application studies about calculating rock-mass parameters have been implemented by back analysis of displacements. In order to improve parameters back analysis
the uniformity design theory is introduced to design training swatch for neural networks
rock-mass mechanical parameters of underground cavern are obtained from measured displacement messages. The back analysis finite element software is implemented based on three key techniques: object-oriented
adaptability and visualization
which can be used as visualized back analysis and forecast tool. Rock-mass parameters back analysis is implemented by mean of “graph-finite element analysis-graph” instead of “data-finite element analysis-data”
it can instruct design and construction in time with monitoring technique and stabilization analysis. It is illustrated that this software is very useful by the example of the underground cavern of a hydropower project.
