坝基由a、b、c三层水平土层组成，厚度分别为8m、5m、7m。这三层土都是各向异性的，土层a、b、c的垂直向和水平向的渗透系数分别是是k_av=0.010m/s，k_ah=0.040m/s，k_bv=0.020m/s，k_bh=0.050m/s，k_cv=0.030m/s，k_ch=0.090m/s。当水垂直于土层层面渗流时，三土层的平均渗透系数为k_vave，当水平行于土层层面渗流时，三土层的平均渗透系数为k_have，请问下列（）组平均渗透系数的数值是最接近计算结果的。

A．k_vave=0.0734m/s，k_have=0.1562m/s

B．k_vave=0.0008m/s，k_have=0.0006m/s

C．k_vave=0.0156m/s，k_have=0.0600m/s

D．k_vave=0.0087m/s，k_have=0.0600m/s
