长大铁路干线设计前期的地质勘察往往是通过钻探取芯的方式来探明路基的地质情况,而钻探取芯的方式存在着投资大、以点代面等问题。相比较而言,高密度电法勘探具有投资小、连续性勘察等特点。本文结合实例对后期钻探对高密度电法勘察结果进行验证,证明了高密度电法在工程地质勘察中的稳定可行性。 Geological prospecting for the design of the Chang-da-Zhuhai railway line is often to find out the geological conditions of the embankment by means of drilling and coring. However, the way of coring drilling there is a problem of large investment and point substitution. In contrast, high-density electrical prospecting with small investment, continuity survey and so on. This paper verifies the results of high-density electrical survey by post-drilling with practical examples, and proves the feasibility of high-density electrical method in engineering geological prospecting.
