摘要/Abstract

摘要：

由于地下发育的岩溶形态空间分布存在不均匀性，导致地表地质调查很难确定地下岩溶含水通道的位置；而一般的地球物理方法受地形或地质条件的限制，在对岩溶含水通道进行探测时存在多解性，往往需要几种物探方法综合判断。本文尝试利用大功率充电法对岩溶含水通道进行快速准确的定位，并通过布设多个充电点来验证异常的可靠性；在布设测线的同时布设以充电点为圆心的弧形测线和平行直线测线，分析对比其优缺点；在数据分析之前分别对数据进行正常场改正和Fraser滤波处理。通过利用多源大功率充电法对洛潭水库复杂岩溶含水通道进行探测后发现：该方法可以快速准确地定位测区内岩溶含水通道的位置及走向，其中弧形测线能够更好地控制整个测区岩溶含水通道的走向，经过正常场改正和Fraser滤波处理后的平行直线测线观测结果也能很好地对异常进行定位；而“多源”观测能更好地甄别有效异常。经钻探及示踪法验证，该方法的探测结果是准确可靠的。

Abstract:

Due to the non-uniformity of spatial distribution of underground karst system, the positions of the underground karst water channels are very difficult to determine by general geophysical investigation method. The general geophysical method is often restricted by terrain and geological conditions, multi-solution is always present during the detection of underground karst water channels, which need to be integrated judegment with several geophysical methods. This paper aims to locate the underground karst water channels quickly and accurately using a high power mise-a-la-masse method. Several charging points were set to verify the reliability of the anomalies of mise-a-la-masse method. Two kinds of line layouts including arc lines with charging point as the center and parallel straight lines were chosen to analyze its advantages and disadvantages. Before data analysis, the normal field correction and Fraser filtering processing were used to deal with the data. The detection of Luotan reservoir complex karst water channels showed that the multi-source high power mise-a-la-masse method could quickly and accurately locate the position and direction of karst water channels in survey zone. The arc lines with charging point as the center could better control the karst water channel direction in the whole survey zone. The parallel straight lines could also position the karst water channels well after the normal field correction and Fraser filtering processing of the data. The ‘multi-source’ method could better identify anomalies effectively. It had been verified by drilling and tracer method, the detecting results of multi-source high power mise-a-la-masse method was accurate and reliable.

Key words: multi-source, high power mise-a-la-masse method, karst water channel, normal field correction, Fraser filtering
