浅层反射波地震法和高密度电法在道路采空区勘查中的应用研究

The Application of Shallow Seismic Reflection Method and High-density Electrical Method to Goaf Investigation

道路采空区勘查是工程物探的一项重要工作,以莱州某路段采空区为研究对象,利用浅层反射波地震法和高密度电法对该路段进行了勘查,成果经钻探验证表明反射波地震和高密度电法都能较准确地探测出采空区的位置和深度,但由于观测误差和干扰的存在,两种方法也可能产生假异常,若将两种方法的探测结果进行综合对比解释,可以减少单一方法的局限性,提高探测结果的准确性。

Road goaf investigation plays an important role in the engineering geophysical exploration.This paper takes a road section in Laizhou as the research object,the shallow seismic reflection method and high-density electrical method are used to investigate the goaf.The drilling results show that both the two methods can accurately detect the location and depth of the goaf,but because of the existence of observation error and interference,the two methods can also direct to false anomalies,if the results of the two methods are comprehensively compared and interpreted,the limitations of the single method can be reduced and the results can be improved.
