摘要
灰岩地区较为突出的特点就是溶蚀现象较为普遍,会产生较多的溶蚀带、溶洞等不良地质现象,会严重地影响到基础工程质量与施工进度。本文介绍了高密度电法结合其他物探手段对灰岩地区溶洞进行的探测,并根据地震波场特征、面波波速、密实度和电阻率特征,对溶洞进行分类判别。结果证明了高密度电法应用在灰岩地区具有较好的实际效果和应用前景。
It is quite common there is corrosion in the limestone region, which results in bad geological conditions. This paper introduces the high density electrical method with other geophysical methods detected karst caves in the limestone regions, classifies and analyzes various karst caves based on seismic wave field, surface wave velocity, density and resistiw ity. The results prove that high--density resistivity method used in the limestone regions has good practical results.
