effective stress law meaning in English

有效应力定律

Based on the biot ' s effective stress theory , and with the method of numerical value experiment , the thesis has studied the microcosmic mechanism of affecting the effective stress coefficient , i . e the microcosmic mechanism of effective stress law by using the elasticity distortion ' s simulating software which is compiled with the method of finite elements . it has been done from the two aspects of affecting the elasticity distortion of rock comprising the insides causation which is the existing configuration of hole and cranny in rock and the outsides causation include the outside pressure and the liquid pressure inside the rock
本文基于比奥的有效应力原理，利用有限单元法的弹性变形模拟软件，通过数值实验的方法，从影响岩石变形的内、外两方面的因素?即内在孔隙裂隙赋存形态和其所受的外载荷及孔隙流体压力出发，研究了影响有效应力系数变化的细观机理，即有效应力规律的细观机理。
