A STUDY ON THE ENGINEERING GEOLOGICAL COUPLING THEORY

Coupling Theory (CT) is a fundamental theory of engineering geology and can be found in every field of engineering geology . It is also a basic guiding index for solving various engineering-geological problems. Its basicthinking way is to make an optimum coupling between engineering system and natural geological system in the process of engineering investigation, design and construction. In this paper an introduction is made to the basic points of CT, including the graphic model, mathematical model, performance steps, cycle and decision-making criteria of the coupling theory, couping degree and risk analysis, and the relationship between coupling theory and other subject, etc.
