冻融循环作用下砂岩的波电特性研究
Study on Wave-Electrical Characteristics of Sandstone under Freeze-Thaw Cycles
摘要
Abstract
The wave-electrical properties and correlation mechanisms of rock masses under freeze-thaw cycles are crucial for assessing the physical properties of rock masses in cold regions and for analyzing and interpreting geo-physical exploration data.This study focuses on sandstone as the research subject,investigating the effects of vari-ous freeze-thaw cycles on parameters such as P-wave velocity,resistivity,and nuclear magnetic resonance(NMR)of rock samples.Additionally,the evolution characteristics of parameters including P-wave velocity,resistivity,po-rosity,and pore size distribution under freeze-thaw cycles were examined.The test results indicate that the P-wave velocity and resistivity of rock samples decrease with an increasing number of freeze-thaw cycles,with the amplitude of change gradually diminishing.Conversely,the porosity of rock samples increases with the number of freeze-thaw cycles,and the amplitude of change gradually increases.For sandstone,the damage variables of P-wave velocity and resistivity are positively correlated with the number of freeze-thaw cycles.关键词
