Discussion of the formation of deep fractures on the left bank of the Jinbing Hydropower Station of the Yalong River

Many deep fractures lie in the left bank of the Jinbing Hydropower Station of the Yalong River.They not only develop in the slope whose dip is opposite to the dip of the strata,but also are beyond the range of the unloading belt.Many people still hold the different opinions whether the deep fractures had formed before the slope loaded off.This paper examines throughly the dynamic and kinematic characteristics and forming time of rod-like calcite veins fibred in the deep fractures,analyzes the sp...
