Planning and Design of Underground Space Use

Whole over the world, up to now, it is difficult to create new space in metropolitan areas. Especially, the complex facilities and people overcrowd urban cities in Japan. In this state, the functions of urban areas do not often work normally. It is necessary to develop urban areas by promoting the concept of threedimensional development that utilizes ground surface and underground spaces as a whole. And it needs that the aboveground space and underground space compensate for each limitation. In this report, the authors studied about the underground spaces to clarify the future prospect of them. At first, the history and the opportunities of the underground spaces are arranged. Secondly, we classified the underground facilities with some examples. And then, the problems for constructing the underground spaces are surveyed by SD method and so on. Finally, it is clarified that the design for underground space should head to create the comfortable space like an aboveground according to future prospects.
