| 摘 要： | 弱渗流结构的力学性质很难用力学方法进行精确测量.提出了用一个分布参数的电学模型来表示弱渗流结构的力学性能,模型参数可通过测量其交流阻抗谱得到.在电学模型的基础上,提出了传输线分布参数模型.传输线分布参数可以用常相角指数来近似表示,常相角指数与分形的维数相关联,可以直接用来表征多孔介质的弱渗流特征.

| Abstract: | It is difficult to accurately measure the mechanical performance of weak seepage structure using mechanical method.It is put forward that the electric model of a distribution parameter is used to represent the mechanical performance of the weak seepage structure.The parameters of the model can be obtained by measuring its AC impedance spectroscopy.Based on the electric model,transmission line distribution parameter model is presented.The transmission line distribution parameter can approximately be represented using constant phase angle exponent.The constant phase angle exponent is related to the fractal dimension of the weak seepage structure pore,and it can directly be used to describe the seepage performance of the porous weak seepage media. |
