Abstract: Traditional seepage calculation and deformation calculation are carried out separately. The traditional method is simple, but it is not suitable for engineering practice with low accuracy. After a lot of scholars research on seepage field and stress field coupling at home and abroad, the coupling theories from different angles were obtained. In order to express the essence of all theories and reflect the difference between theories, the flow-deformation coupling theory was classified and evaluated from 4 aspects: computational domain coupling, basic unknown coupling, parameter coupling and constitutive relation coupling. The conclusion has drawn that the computational domain coupling is a simple computational method but with low precision; the basic unknown coupling has a perfect theory system; the parameter coupling is only established for a certain type of soil, and lacks universality; the constitutive relation coupling should be further studied in cohesive soil.

Key words: geotechnical engineering, flow-deformation coupling, computational domain, constitutive relationship, basic unknowns

摘要: 传统的渗流计算和变形计算是分开进行,方法虽然简单,但不符合工程实际且精度较低。经过国内外的学者在渗流场和应力场耦合问题上的大量研究,得出了从不同角度开展的耦合理论。为了体现出每种理论的本质和不同理论之间的区别和联系,对流固耦合理论从计算域耦合,基本未知量耦合,参数耦合和本构关系耦合4个方面进行了分类、评价。得出结论计算域耦精度较低但计算简便,基本未知数耦合理论完善,参数耦合仅针对某一类土建立,缺乏普遍性,本构关系耦合需进一步在黏性土中研究。
