WebThe Biot-Willis coefficient is a key component associated with the effective stress field, where it represents the proportion of fluid pressure that counteracts the confining stress. To properly estimate the Biot-Willis coefficient, we require knowledge of the more fundamental building blocks of a rock mass that go beyond the elastic domain ... Web目 录 2.4.4 蓄水系数 由于流体可以通过孔隙压力的增加或减少从孔隙骨架中注入或提取,因此引入蓄水系数的概念是有用的(Green and Wang,1990) ,它可以定义为获得(或损失)的流体体积由于孔隙压力单位增加(或减少),每单位体积的孔隙弹性骨架。 可以证明,由Biot(1956,1957) 引入的Biot模量(Biot modulus ...
