摘要: 在实际工程中,对于裂隙土的边坡、道路桥梁工程及基础土体,渗流对其承载能力、稳定性有显著的关联作用。裂隙土体渗流模型的研究并不少,现就几种目前最主要的裂隙土体渗流模型研究现状及其特点和不足进行了阐述,并在上述基础上提出了一些新的展望。等效连续介质模型是目前应用最为广泛的模型,但它也有自己的缺点,一些张量的确定不够准确,需要进一步研究,如裂隙岩体几何参数、有效孔隙度以及等效渗透张量等。从细观力学结构入手研究渗流耦合模型是一个极其明智的出发点,其必将极其具有重大的理论意义和实用价值。

Abstract: In the engineering practice such as slopes, highway embankments and bridge projects, the seepage in fissured soils has a coupled effect on the stability, bearing capacity. This paper reviews the advantages and disadvantages of several main seepage models in fissured soils. The equivalent continuum model is the most widely used model. The disadvantages of this model are: inaccurate description of some tensors, such as, geometry parameter of fissured media, effective porosity and effective seepage tensor. The coupled models that starting from the micromechanics have very promising applications.
Key words: Fissured Soils, Seepage Models, Research Progress, Coupled Effect
