中文摘要:
      天然源面波勘探是从自然界的各种微小振动中提取出瑞雷面波,经过面波频散曲线的反演得到岩层速度结构,达到推测地下岩层和构造分布状况的目的。该方法克服了人工源激发困难的问题,对场地适应性强,有效探测深度较大,探测结果具有分辨率高、抗干扰能力强等特点。文章以扎西康矿区采空区勘察中的应用为例,介绍了天然源面波法特点、优势及应用效果。
英文摘要:
      The natural source surface wave exploration uses the detector to collect all kinds of natural weak vibrations from which Rayleigh surface wave is extracted. Inversion of the frequency dispersion curves is made to obtain velocity structure of rocks and postulate distribution of the strata and structure underground. The technique overcomes difficulties of the artificial source excitation and limit of the working site. The effective detection gets to deeper with high resolution and strong anti-interference. Taking the mined-out area in Zhaxikang mining area as an example, this paper analyzes application characteristics, advantage and effect of the natural source surface wave method.
