摘要
前期对坝址区发育深部破裂位置进行纵向和横向勘探,均是点、线上的揭露,深部破裂在空间上的延展情况未切实查明,尤其对于隐蔽性较大的、出露条件不好的硐段,往往前期很难全面揭示。依平硐揭露深部破裂为基础,采用地震波CT成像技术,提出以地震波速(小于4 500m/s)、断层作为终止边界的综合辨识方法。
Early development of the dam site area of deep longitudinal and transverse rupture location exploration, are exposing the point, line, deep-seated fracture in space extension without effective identification, especially for larger hidden, exposed poor conditions the cave segment, is often difficult to fully reveal preliminary. According to Adit expose deep rupture based on the use of seismic wave CT imaging technology, made in seismic velocity (less than 4500m/s), fault identification method terminates as a comprehensive border.
