AbstractThe stress-strain-permeability behavior of artificial specimens with different pore proportioning was investigated electrohydraulically by servo-controlled MTS 815 rock test system. The influences of pore proportioning, porosity and seepage on rigidity and peak strength of artificial specimens were systematically studied by comparing testing results. The relationship between pore proportioning, porosity and permeability was thus obtained to set up an equation expressing how the hydraulic pressure and porosity weaken the rigidity and peak strength of artificial specimens. A reference was therefore provided to describe quantitatively the relationship between rock's porosity, permeability and peak strength. Experimental results showed that the coarse particles in proportioning and macro pore affect obviously the porosity and initial permeability and water weakens the rigidity and strength of specimens more significantly with increasing porosity.
應用電液伺服巖石力學試驗系統,研究了不同孔隙配比的人工巖芯試件的應力應變滲流特性,比較系統地分析了孔隙分布配級、孔隙度、滲流作用對強度、剛度的影響.試驗得到了孔隙配比、孔隙度與初始滲透性的關系,建立了水壓和孔隙度對試件強度弱化的關系方程,對于定量描述孔隙結構與滲流率、試樣強度的關系,具有一定的參考價值.試驗結果表明,粗顆粒比例和大孔徑孔隙對孔隙度和滲透性影響較大,隨著孔隙度增加,水對試件的強度弱化程度更加顯著.
