摘要
针对济南地铁勘探中提出的各种要求和不同区域的复杂地质特点,使用ZBL-U520A型非金属超声检测仪测定地质勘察钻孔孔壁岩体的纵波波速,从而计算了岩体完整性系数,根据相关规范对岩体的完整性进行了研究评价,取得了良好的效果。
According to various requirements and the complex geological characteristics of different zones in Ji＇nan subway exploration,ZBL-U520A nonmetallic supersonic instrumentation was used to the determine the p-wave velocity of rock mass around geological investigation drill holes.Thus the rock mass integrity index could be computed.The rock mass integrity was evaluated by the index based on the related standard,which has made the good progress.
