【摘要】 通过对坝址勘探平硐中岩体张开结构面的精确统计以及对岩体硐壁及钻孔的波速测试,初步查明了坝址区松动岩体的发育深度,并用物理模型模拟坝址区地震条件,进一步验证了坝址区松动岩体的发育深度。更多还原

【Abstract】 The earlier stage investigation indicates that there exists large scale dynam-relaxed rock mass at Daliushu dam site.The developed depth of dynam-relaxed rock mass in the dam site area is basically found by precise statistics of the rock mass stretch constructional face in the exploration adit and by tests of the rock mass adit wall wave velocity and borehole wave velocity.It is further verified by using physical model to imitate the seismic condition in the dam site area.更多还原
