In this paper, we present results of the fundamental study for identification analysis of the Young's modulus used in stability evaluation of ground structure. In general, though the stability evaluation of ground structure is carried out by the shear strength reduction method, the value of the Young's modulus used in this evaluation is estimated by the result of the standard penetration test. Therefore, it is necessary to know the suitability of the Young's modulus, because the result of the shear strength reduction method depends on the prescribed Young's modulus. As for the introduction to obtain the appropriate Young's modulus, we investigate about the identification method of the Young's modulus based on the adjoint variable method.
