摘要:
本文介绍了一种新的隧底隐伏岩溶探测方法-基于共中心点道集的二维瞬态面波方法。基于共中心点道集(CMPCC)的二维瞬态面波方法观测系统采用固定排列和滚动排列两种方式,数据处理时采用叠加的方式来压制随机噪音干扰,从而提高了数据质量,同时还具有较高的横向分辨率。本文采用钻孔的方式来固定检波器,从而保证了检波器和地面的耦合;采用30 kg尼龙棒敲击橡胶垫的方式达到激发低频信号的目的,从而保证了数据质量。后续钻探验证表明,面波处理结果和钻探结果具有较高的一致性,证明了该方法在隧底隐伏岩溶探测中具有较好的效果。
Abstract:
A new detection method for the hidden karst at the bottom of tunnel is introduced in the paper, which is the 2D transient surface wave method on the basis of CMPCC. Fixed arrangement and rolling arrangement are adopted for the observation system of the 2D transient surface wave method. The superposed method is adopted to suppress the random noise interference during data processing, so as to improve the data quality, and the method has high lateral resolution. The drilling method is used to fix the detector, so as to ensure the coupling between detector and the ground. The low frequency signal is excited by tapping the rubber pad with 30 kg nylon rod to ensure the data quality. The subsequent drilling verifies that the processing results of surface wave are consistent with that of drilling, which proves this method has a good effect in the detection of hidden karst at the bottom of the tunnel.
