摘要
参考二维平行板间不可压缩粘性流体的运动方程,分析推导了宾汉浆液在等宽光滑倾斜裂隙中的流动方程。通过分析该流动模型发现:宾汉浆液流速随时间逐渐降低。压力越大,浆液流速越大,则浆液渗透更远。并不是裂隙倾角越大,则宾汉浆液流速越大。在其他参数相同情况下,裂隙宽度越大,浆液流速越小;浆液粘度越大,或初始剪切粘度越小,或浆液密度越大时,浆液流速也会越小。
In accordance with the Navier-Stokes equation between planar plates,the flow equation of the Binghamian grouts flowing in smooth and inclined fissures was deduced.The model indicates that the velocity of the grouts gradually reduces with time.And the greater the pressure in the grout,the greater its speed is,as a result,the Binghamian grouts has a further infiltration.The flowing velocity of Binghamian grouts has nothing to do with fissure inclination.In addition,in the circumstance of the same parameters,t...
