本文提出岩体结构面适应性平行板模型和该模型的参数确定方法——三段压水试验新解释，新的模型有益于克服将结构面圆盘模型应用于地下水模拟中的局限性；基于结构面起伏度对地下水流动的影响，导出了起伏度修正系数解析表达式。
This paper presents an adaptive parallel plate model of rock mass structural plane and a method to determine the parameters of the model - a new interpretation of the three-stage water pressure test. The new model is helpful to overcome the limitations of the application of structural circular model in groundwater simulation. The influence of structural surface roughness on the groundwater flow is derived and the analytic expression of the roughness correction factor is deduced.
