Abstract:

During the construction of Miaowei Hydropower Station, the toppling and deformation of dam foundation appeared several times. On the basis of investigating the geological, hydrological and meteorological data of the dam site, the basic characteristics of rock mass structure and rock toppling and deformation, the stability and instability mechanism of toppling rock were analyzed. So the toppling and deformation law of left bank dam foundation was obtained. In combination with the field practice, a series of necessary engineering measures were adopted to reinforce the dam foundation. The relevant experiences can be used for reference of similar engineering in future.

Key words: toppling deformation, stability analysis, reinforcement, Miaowei Hydropower Station
