Through the computational analysis, the amended calculation model has the similiar result to the Eaton method while calculating the pore pressure. When applied to the work area, the calculating result is superior to the original equivalent depth method.

• 通过计算实例分析，该修正计算模型具有和Eaton法计算地层压力相近的结果，将该方法应用于研究工区，计算结果优于一般等效深度法。
