The reasons forming abnormal formation pressure mainly includes digenesis, thermogenesis, biochemical action, tectonic action, dialysis, and fluid density difference action.

形成异常地层压力的原因主要有成岩作用、热力作用、生化作用、构造作用、渗析及流体密度差异作用等。

The dependences of seepage velocity and bending strength on agglomerant content, forming pressure, particle diameter of the aggregate, soaking time, firing temperature and so on were discussed.

分别从外加粘结剂百分数、成型压力、骨料粒径、保温时间、烧成温度等因素对渗水砖的渗水速度和强度的影响进行了探讨。
