APPLICATIONS OF GREY MODEL IN LINEAR DEFORMATION MEASUREMENT OF ROCK MASS
灰色模型在岩体线法变形测量中的应用

The linear deformation measurement is a useful way in rockmass monitoring, which can obtain the detormations of many places along the measuring line by setting a measuring mark every meter. To use the survey data well, and let it play more important role in engineering, the Grey Model is used to analyze the data. Combining with the features of linear deformation measurement, the model is used to describe the deformation distribution, monitor its behavior in important parts, and predict the maximum deformation. With linear deformation survey data on the north slope of the permanent ship lock of the Three Gorges Project, these methods are proved to be rational and feasible.
