Abstract:During the construction of underground powerhouse of Guandi hydropower station, the influence of blast on side wall is controlled strictly, the design is optimized, the reasonable blast parameters are choosed, the support is carried out timely and the elastic resistance of the rock are applided completely. The design control indexes are meet the requirements of the design drawing, the construction codes and the technical clauses.
Keywords:underground powerhouse  high stress  high side wall  bad geology  cross tunnel section  excavation technology
