摘要
基于煤岩瞬态渗透法,对煤岩试件进行蠕变-渗流耦合试验;对于不同的围压、孔压条件下,通过蠕变破裂过程中的渗透性试验,拟合出相应蠕变-渗透率曲线,揭示渗透率的变化和煤岩试样的蠕变损伤的一致性;据Issac Newton提出的均差法,在蠕变-渗透率耦合曲线上给出一定数量的关键点和试验点上进行插值,获得渗透率-蠕变拟合方程。
Based on the coal（rock） method of transient penetration,triaxial creep-seepage coupling experiment were carried out in different confining and pore pressure condition.By the creep rupture process of permeability experience,the curve of creep-permeability was fitted out,which revealed consistency between the sample of coal（rock） permeability changes and creep damage.According to Issac Newton＇s all differential method,a certain number of points was given on sites of creep-permeability coupled curve and interpolating,the permeability-creep equation was got.
