迄今为止 ,地质作用的深度通常是用压力除以密度来计算的。这种方法只在假设岩石处于静止的液体状态下才是正确的。然而 ,实际上从浅部地壳直至地幔深处的岩石都是固体状态而不是液体状态 ,且粘性系数随深度递增。实测数据表明 ,地下水平压应力总是大于垂直压应力 ,说明构造力在量值上超过重力。所以 ,在地壳中进行地质作用深度的测算必须把岩石看作是固体并依据固体物理理论。因此 ,吕古贤等在文献 [1 6 ]中提出的深度测算方法 ( 1 998)是有意义的。
To date, the depth of geological effects is usually calculated by dividing the pressure by the density. This method is correct only assuming that the rock is in a quiescent liquid state. However, in fact, the rock from the shallow crust to the depths of the mantle is in a solid state rather than a liquid state, and the viscosity coefficient increases with depth. The measured data show that the horizontal compressive stress is always greater than the vertical compressive stress, indicating that the structural force exceeds the gravitation in magnitude. Therefore, the calculation of the depth of geological processes in the earth’s crust must treat the rock as solid and based on solid-state theory. Therefore, Lu Guxian et al [16] proposed in depth estimation method (1 998) makes sense.
