摘要

摘要: 针对桂北地区泥质粉砂岩在干湿循环作用下的力学性能劣化问题，开展不同干湿循环次数的单轴抗压强度试验与SEM试验，并基于能量演化规律确定了泥质粉砂岩的完全压密点，构建了泥质粉砂岩分段损伤本构模型。研究结果表明：（1）在经历5次干湿循环后，泥质粉砂岩单轴抗压强度和弹性模量分别下降了90.7%和81.5%，破坏模式由剪切破坏转变为拉−剪复合破坏。（2）确定耗散能等于弹性应变能的点为完全压密点，压密应变随干湿循环次数增加呈线性增大。（3）分段损伤本构模型拟合结果与试验数据的匹配度较好，可更准确地描述干湿循环作用下泥质粉砂岩的变形破坏特性。研究结果为桂北地区历经降雨−曝晒循环的边坡稳定性提供了数据支持和理论参考。

Abstract: Aiming at the deterioration of the mechanical properties of mud siltstone in northern Guangxi Province under the action of wet and dry cycles, uniaxial compressive strength tests and SEM tests with different numbers of wet and dry cycles were carried out, and based on the law of energy evolution, the complete compaction point of mud siltstone was determined, and the segmental damage constitutive model of mud siltstone was constructed. The results show that: (1) After five dry and wet cycles, the uniaxial compressive strength and modulus of elasticity of the siltstone decreased by 90.7% and 81.5%, respectively, and the damage mode changed from shear damage to tensile-shear composite damage. (2) The point where the dissipated energy is equal to the elastic strain energy is determined as the complete compaction point, and the compaction strain increases linearly with the increase of the number of dry-wet cycles. (3) The fitting results of the segmental damage constitutive model match well with the experimental data, which can more accurately describe the deformation and damage characteristics of muddy siltstone under the action of wet and dry cycles. The results of the study provide data support and theoretical reference for the stability of slopes subjected to rainfall-exposure cycles in Northern Guangxi.
