摘要:
采用电阻率成像法探讨了室内实验尺度上岩体中盐溶液的入渗过程。在岩柱试样上进行蒸馏水和盐溶 液的入渗实验,在入渗过程中通过多通道高密度电阻率勘测系统对岩柱的电性特征在三维空间上进行动态监 测。然后对入渗过程岩柱进行电阻率成像,从而获得不同时刻岩柱中的电阻率分布。各勘测截面上电阻率的分 布和变化基本反映了岩柱内盐溶液的时空变化特征,表明电阻率成像法动态监测室内实验尺度岩石中盐溶液的 入渗是可行的,岩柱5个截面的电阻率图像表明溶液的入渗是不均匀的。
Abstract:
The infiltration process of salt solution is investigated in a laboratory scale rock block using electrical resistivity tomography. First, an infiltration experiment with distilled water and salt solution is made on a rock column, and the infiltration process is monitored with a multi-channels high-density electrical resistivity tomo- graphy system. Then, an electrical resistivity tomography for the rock column is constructed. The electrical re- sistivity distributions at different planes reflects the spatial variations of salt solute in the rock block. The results indicate that actively monitoring salt solution infiltration process in a sample scale rock block with high-density e- lectrical resistivity tomography is feasible. The electrical resistivity images indicate that the infiltration in the rock block is an asymmetrical process.
