摘要：

为了探究高温水冷循环后玄武岩的静态压缩力学特性及宏微观损伤演化规律,利用HUT-106A试验机对3组温度(100、300、450 ℃)下高温水冷循环(1、3、5、7次)处理后的玄武岩试样开展静态单轴压缩试验,并借助SEM对试样压缩断口进行微观试验。结果表明,温度一定时,随着循环次数的增加,玄武岩的质量、波速、纵波峰值强度和弹性模量均呈劣化趋势,应力-应变曲线逐渐变缓,破坏的突发性和脆性减弱,渐进性和塑性增强,在450 ℃水冷循环7次后其劣化程度最为显著。在损伤破坏方面,温度一定时,循环次数的不同,玄武岩的宏微观破坏形式均存在差异,并在450 ℃水冷循环7次后发生塑性破坏;在高温水冷循环和荷载的共同作用下,玄武岩试样的的总损伤变量演化曲线表现出非线性的特征,且曲线随着循环次数的增加而逐渐变缓,表明玄武岩逐渐由脆性向塑性转变。研究成果可供矿山地下工程的安全稳定性分析参考。

Abstract:

Static uniaxial compression tests were conducted on basalt samples using the HUT-106A testing machine to investigate the mechanical properties and macro-micro damage evolution laws of basalt subjected to high-temperature water-cooling cycles. The tests involved water-cooling cycles at three different temperatures (100, 300, and 450 ℃) with varying cycle times (1, 3, 5, and 7 times). The compressive fractures of rock samples were observed using SEM. Results reveal that when temperature remains constant and the number of cycles increases, basalt exhibits deteriorating trends in mass, wave velocity, peak strength, and elastic modulus. The stress-strain curve decelerates, and the suddenness and brittleness of failure weaken, whereas the gradualness and plasticity of deformation enhance. The degree of deterioration is most pronounced after seven water-cooling cycles at 450 ℃. In terms of damage, the macro and micro failure modes of basalt vary with the number of cycles at a constant temperature. After seven water-cooling cycles at 450 ℃, basalt exhibits plastic failure. Under the combined action of high-temperature water-cooling cycles and load, the total damage evolution curve of basalt displays nonlinear evolution characteristics, with the curve gradually decelerating as the number of cycles increases. This indicates that basalt transitions from brittle to plastic behavior with increasing cycle times.
