- By maintaining drilling fluid pressure above rock formation pore fluid pressure, there is a natural tendency for the drilling fluid to enter permeable rock in the formation. 而如果保持钻井液压力高于岩层孔隙流体压力,钻井液就会出现向岩层的透水岩石中渗入的自然趋势。

- Besides, the undrained shear strength was increased slightly due to the negative pore pressure. 不排水条件下由于负孔隙水压力的存在，土样的表观强度略有增大。
- In the meantime, the pore pressure also increased with the increase of confining pressure. 同时，孔隙水压力值也随着周围压力的增大而明显增大。
