Abstract

In this paper, the deformation characteristics of underground powerhouse of Wudongde Hydropower Station is obtained by the field observation. Two theoretical models, triangular block and the four-sided simply supported plate and beam models, are put forward to analyze the deformation characteristics of the side wall. As well, the numerical method UDEC software is used to verify the correctness of the theoretical analysis. The above three methods are used to analyze the severe deformation of the upstream side walls, which is near 7# and 8# units after the roof blasting of L3 adit. The deformation of the downstream arch bases near 9# and 10# units is more severe than the upstream side walls near 7# and 8# units. After the construction process was changed, no serious deformation occurred in the follow-up parts of the upstream. Based on that, the following results are shown. First, the steep dip angle of the layer cuts the surrounding rock into the triangular cantilever blocks, which reduces the integrity of the surrounding rock. The serious deformation of the upstream side wall near 7# and 8# units are caused by the weakening of the stability of the triangular cantilever block caused by the explosion of the L3 adit. Second, the maximum deformation of the surrounding rock of the main powerhouse decreases with the increase of the steep dip angle of the layer. Third, the weak material at the arch seat at the downstream of 9#–10# unit leads to the deformation of surrounding rock greater than that of 7# and 8# unit upstream side wall. The study on the deformation mechanism of underground powerhouse in Wudongde Hydropower Station can provide experience reference for projects with similar geological conditions.
