摘要
以唐山市二环隧道工程勘察为例,利用瞬变电磁法进行浅层采空区、岩溶探测的有效性试验研究。充分利用瞬变电磁法具有抗干扰能力强、横向分辨率高、受地势影响小、不受接地条件限制等特点,查明了该测区采空区、岩溶的位置及分布情况,后期钻探验证表明所采用的方法是行之有效的。
Taking tunnel engineering investigation of Second Ring Road of Tangshan for example ,this paper utilizes the transient electromagnetic method to do an effective experiment of detecting shallow goaf and karst .It makes full use of the transient electromagnetic method with a strong anti-interference ability ,the high transverse resolution ,little impacted by ter-rain,not restriction by grounding conditions and other characteristics .It detects the position and distribution of the goaf and karst.Finally,through drilling which has tested effectively that the comprehensive integrated geophysical exploration is useful .
