| Abstract: | An inverse method for identification of elasticity moduli related to rock mass and linings of underground: caverns is presented on the basis of measured displacements obtained from underground excavations by using Levenberg-Marquardt optimization method.The emphasis is placed on the implementation principle and numerical technique, and an example is given to demonstrate the validity and correctness of the method. |
