【摘要】 某水利枢纽右坝头自然边坡由于厂房进水口的开挖,成为中长的超高急坡或陡坡,在右岸边坡进行帷幕灌浆中,出现灌浆致裂岩体问题,发现追踪顺边坡的构造溶隙Kg9及与之平行的卸荷裂隙的张性裂缝,同时边坡坡面上亦发现沿层面软弱面出现的压扭性裂缝。为此对水库蓄水后边坡的稳定进行了3D弹塑性有限元计算。更多还原

【Abstract】 In a hydroelectric project,a steep highwall slope is formed on the right bank as a result of the excavation of the water intake of power tunnel.Tensile cracks along the structure plane Kg9 and shear cracks along the bed surface are appeared on the right bank slope during curtain grouting.For this reason,the stability of right bank slope is analyzed by use of 3D FEM.更多还原
