摘要/Abstract

摘要： 有别于传统的工程地质材料——土，土石混合体作为一种新兴的岩土介质材料正吸引着越来越多研究人员的关注。基于文献阅读与搜集，从块石物质来源角度将土石混合体的地质成因主要分为风化作用、冻融作用、冲刷作用、岩溶作用等4类；其次，对土石阈值、“土”与“石”的导电特性、“土”与“石”的联接与占比进行讨论；然后，从含水量、密实度、土石比、孔隙率等几个不同的影响因素出发，对不同影响因素下土石混合体电阻率特性的表现规律进行总结；最后，对当前土石混合体电阻率特性研究中存在的问题与不足、未来的研究重点进行了探讨。

关键词: 岩土工程；土石混合体；电阻率特性；地质成因；研究进展

Abstract: Different from the traditional engineering geological material—soil, as a new geotechnical medium material, the soil-rock composite medium is attracting more and more researchers’ attention. Based on the literature reading and collection, from the perspective of the source of the block rock material, the geological origin of soil-rock composite medium was mainly divided into four types: weathering, freezing-thawing, scouring and karstification. Then, the soil-rock threshold, the electrical conductivity of soil and rock, the connection and proportion of soil and rock were discussed. Thirdly, starting from several different influencing factors, such as water content, compaction degree, soil-rock ratio, porosity, the performance rules of resistivity characteristics of soil-rock composite medium under different influencing factors were summarized. Finally, the problems and shorts in the current research on resistivity characteristics of the soil-rock composite medium and the future research focus were discussed.

Key words: geotechnical engineering; soil-rock composite medium; electrical resistivity characteristics; geological origin; research progress
