摘要：

The parameters of tunnel surrounding rock are very important to the design, construction and stability analysis of tunnel engineering. Now there are some shortcomings in the methods to obtain them. It is believed that displacement back analysis method can solve the problem, but there are still some defects in it. Aiming at the above problems, the article establishes a network of intelligent back analysis of tunnel surrounding rock displacement (IBATSRD) which is based on ANN (artificial neural network) toolbox. Finite element method and orthogonal design method are used to get the training samples, which ensure that the samples are in accordance with the facts, and have uniform dispersivity and symmetrical comparability. At last, the authors introduced an example of IBATSRD's application. The result indicates that the method has high computation precision, above 90%, and has overcome some flaws of traditional back analysis methods. The method is recommendable.
