| 摘 要： | 超前冲击钻钻探是岩石隧道中一种轻便、快捷、成本较低的直接地质预报方法,通过钻进数据可以判断掌子面前方地层的状况,降低地质事故的发生率.目前在地质钻预报方面主要是通过不在同一平面的三个钻孔来预测地层空间位置,对于地层性质的预测通常是定性的.作者以一种钻机为基础,进行了大量的现场实测,根据现场实测数据、实验室测试数据、现场的地质描述,分析了冲击钻钻速与岩石抗压强度、围岩类别的定量关系,建立了钻速与岩石BQ的统计关系式,这为隧道变更设计,预防事故提供了坚实的数据基础.

| Abstract: | The advanced percussive drilling exploration in the rock tunnel is a direct geologic forecast method which is convenient,fast and inexpensive.The geological condition ahead of the workface can be determined by the data obtained from drilling,so the geologic accidents can be avoided to rome degree.By this method the location of strata can be forecasted through three boreholes not in a plane.The prediction ~ strata property is usually a qualita- tive one.In this paper,based on one type of percussive drill and... |
