Deformation Characteristics of High Slope of Cihaxia Hydropower Station
The geological conditions of high slope is detailed, the main deformation characteristics of high slope are described. Based on the above, it is known that the rock mass unloading-loosing and toppling deformation accompanying the creeping along bedding plane or fault mainly happen in the upper and middle portion of the high slope, especially in the upper portion. These deformations have other features in the middle portion of the slope: the deformed rock mass rarely appears the bending, but exists an obvious weak plane out of which the rock stratum and tensile fissures mostly dip to the inner of the slope, suggesting the deformation mainly is toppling and tensile-cracking; inside of the weak plane the dip direction is opposite to the outside. The deformation of the upper portion is different from the middle one in which there has a lot of tensile fissures which attitudes are variable and the degree of the breaking and loosing is largely higher than the middle portion of the high slope.
