摘要
Many deep fractures lie in the left bank of the Jinbing Hydropower Station of the Yalong River. This paper examines throughly the dynamic and kinematic characteristics and forming time of rod-like calcite veins fibred in the deep fractures, analyzes the spatial and temporal distribution characteristics of valley terraces in this area. It puts forward and proves that the deep fractures were not caused by earthquakes, nor the results of the slope unloading, but were produced under the effect of the impulse tensile prolonged tectonic movement.
