电测深法和电磁波CT法在采空区注浆加固效果检测中的综合应用

本文分别介绍了电测深法和电磁波层析成像方法,两种方法操作简单且能够详细反映采空区注浆加固效果。综合应用两种方法对铁路地下采空区加固效果进行检测,结果均表明了在线路的K0+278～K0+450段加固效果良好,两种检测方法检测结果具有一致性。证明将两种检测方法综合应用在采空区加固效果检测是合理的、可行的,为今后其他同类的检测效果提供了可借鉴的经验。

APPLICATION OF THE COMBINATION OF ELECTRIC SOUNDING AND ELECTROMAGNETIC CT IN DETECTION OF GROUTING QUALITY

There are many methods in detection of grouting quality in mine cavities. However, there are no mature and credibility technical methods. This paper introduces a method combining DC sounding and Electromagnetic CT techniques. The two techniques operate simply and could reflect the grouting quality of cavities in detail. The combined method has applied to the detection of grouting quality in mine cavities along a railway The results indicate that the grouting quality is well at the segment K0 278~K0 45. The results of the two techniques are consistency. It is proved that the combined method is reasonable and feasible for detecting the grouting quality at mine cavities. The case study in this paper can provide experience for testing other homogeneous reinforce effect.
