高密度电阻率法对盐渍土的检测效果分析

High-density Electrical Detection Effect of Saline Soil

在天然状态下,盐渍土为较好的地基,一旦因自然条件的改变就会产生严重的溶陷、膨胀和腐蚀,使建筑物裂缝、倾斜或结构被腐蚀破坏。本文主要从高密度电阻率法和地质雷达法的探测精度问题展开讨论,通过对瓜州干河口风电场盐渍土所进行的高密度电阻率法和地质雷达法无损检测数据的分析和对比,表明高密度电阻率法对盐渍土的检测效果较地质雷达法更优。

In the natural state,saline soil is a good foundation.Once it is changed due to natural conditions,there will be serious immersion,dilation and erosion,thus leading to the severe damage to buildings.Through the analysis and comparison of the data obtained by high-density resistivity method and ground penetrating radar method for a wind power station in Guazhou,this paper discusses the detection accuracy of the two methods.The results indicate that high-density resistivity method has the advantage over ground penetrating radar method in the detection effect of saline soil.
