Abstract:

The Xiluodu underground powerhouse cavern’s scope is huge, and the main plantand the transformer room are 28.4m and 25.0m in span. Based on the relaxation coefficient function, a new calculation algorithm of the parametric regression of the surrounding rocks was  presented to simulate the disturbance and relaxation phenomena of the surrounding rocks caused by excavation. Based on the above feedback analysis theory, the tracing feedback and prediction analysis of the staging excavation between the 1st to 10thexcavation were performed.After the parameter adjustment and feedback analysis of the 1stto10thexcavation, the precision of the prediction of the typical sections canreach asatisfactory level, which proved the availability of this method in actual construction.
