摘要
为研究雷灾防御工程中的重要参数——多层土壤结构分层参数,在两个已知土壤结构的试验场,分别采用Wenner四极法和非等距四极法、对称非等距四极法测量试验场的土壤电阻率,利用CDEGS软件反演土壤结构模型,发现对于非均匀多层土壤,利用非等距四极法和对称非等距四极法的测试数据反演的土壤结构分层结果比使用Wenner法的结果更精确,与地勘结果具有良好的对应关系,且对称非等距四极法更优于非等距四极法。
In order to study the layering parameters of multi-layer soil structure which was an important parameter in lightning disaster prevention,this paper used two sites with uniform and inhomogeneous soil structures.The Wenner quadrupole method and the non-equidistant quadrupole method and the symmetrical non-equidistant quadrupole method were used respectively for soil resistivity measurement,and then CDEGS software package was used to invert the multi-layer soil structure model. The results showed that in inhomogeneous soils,there was a good correlation between soil structure stratification and geological survey data retrieved using non-equidistant quadrupole method and symmetric non-equidistant quadrupole method. But,the symmetrical non-equidistant quadrupole method was better than non-equidistant quadrupole method at the inversion of soil structure stratification.
