| 摘 要： | 土的电阻率相关参数指标与土的工程力学指标紧密相连,并可反映土的一些特殊性质,如土的污染特征、地基液化特征等。本文首先简要介绍了土的电阻率理论,分析了土电阻率的室内外测试原理与方法。在归纳相关文献与工作的基础上,探讨土电阻率法在地基处理及其相关领域中的应用。深入分析了电阻率法在水泥土搅拌桩质量评价、地基处理效果评价、地基液化评判、压实土质量评价以及地基污染中的应用特征以及评价方法。并讨论了土的电阻率理论研究中存在的问题,展望了土电阻率理论的研究与应用前景。

| Abstract: | Studies have shown that the electrical resistivity of soil can well represent its geotechnical properties,such as characteristics of soil contamination and ground liquefaction potential.This paper reviews the theory of soil electrical resistivity and measurement of soil electrical resistivity both in the lab and in the field.With summarizing literature works,the application of soil resistivity method for the ground improvement engineering is introduced,particularly in the evaluation of cement-treated soil column,ground improvement effect,potential of ground liquefaction,properties of compacted soil and ground contamination.Finally,the problems and the application prospects of the electrical resistivity study are discussed. |
