| 摘 要： | 基于城市隐伏活断层钻孔联合剖面探测的多次实践,总结出一种优化的断层定位方法--对折法.其步骤为:首先实施剖面两端的钻孔,在确保断层在两孔间之后,在两孔中间位置布设第3孔;继续确定断层所在区段,然后在其间二分之一处布设下一钻孔,依次类推,逐渐限定出断层的准确位置.同时,引入孔间标志层位坡降这一量化指标替代落差分析,并归纳...

| Abstract: | In this paper,an optimized drilling exploration method,the doubling section method,was summarized after many composite drilling section explorations of buried active fault in urban areas.Operation steps of this method are as follows: Firstly,drill a borehole at each of the two ends of the drilling section to make sure that fault is between the two boreholes,then,drill the third borehole at the middle of the two holes;and secondly,confirm again the segment where the fault is and drill the next borehole in th... |
