砂岩弹塑性力学特性的水物理化学作用效应——试验研究与本构模型
|
摘要
针对干燥、饱水、蒸馏水以及不同离子浓度和pH值水溶液循环流动作用至水–岩反应平衡后的砂岩试件,开展一系列单轴压缩试验和CT损伤测试,获得这些不同状态及水溶液作用后砂岩试件的应力–应变关系全过程曲线和CT扫描结果;分别研究砂岩弹塑性力学特性包括应力–应变关系、弹性模量、峰值强度及残余强度的水物理作用和水化学作用效应与机制;基于CT检测结果开展相应的水物理化学损伤分析;在此基础上,通过分析水物理化学作用对砂岩应力–应变关系的影响特征与规律,探讨并采用改进的Duncan模型来描述存在水物理化学作用效应的砂岩非线性弹性变形行为。研究结果对于水–岩相互作用及相关领域的理论与应用研究,具有良好的促进与借鉴作用。
A series of uniaxial compression tests and computerized tomography(CT) scanning tests on dry,saturated sandstones,and the sandstones with hydro-physicochemical influencing effects due to the circulating flow of distilled water and different hydro-chemical solutions are conducted.The corresponding complete stress-strain curves and CT scanning results are obtained.The hydrophysical and hydrochemical influencing effects on the elastoplastic mechanical behaviors of sandstone,such as stress-strain relationship,elastic modulus,peak strength and residual strength are derived.The hydrophysical and hydrochemical influencing mechanisms of water-sandstone interaction are studied.The hydro-physicochemical damages of sandstones are analyzed based on the CT scanning results.The modified Duncan model is used to describe the mechanical behaviors of sandstones with different hydro-physicochemical influencing effects.This study has a useful reference to the theoretical and applied research in the field of water-rock interaction.
