An underground space to store is studied on the shape and the mechanical behavior after excavation. The shape of under ground space must be determined under the conditions to keep the functions, to be safe and to be economical. In the case of underground space for storing, it is required that the space has the maximum volume under some conditions. If we assume that the space has such form as a long straight tunnel which section is uniform along the longitudinal direction, the section area of the space is required to be maximized under some constraints, taking the purpose of the space into account. In this paper, taking just only mechanical conditions after the excavation into account, we study the desirable shape of underground space constructed in isotropic or anisotropic bedrock. Then, a fundamental investigation of the relationship between the shape and the mechanical behavior is described.
