PROBLEM TO BE SOLVED: To provide a method for constructing an underground structure and the supporting structure of a ground structure, which are proper when the underground structure such as an underpass, a subway or the like are built under a track and can be constructed rationally as the present condition of the ground structure are left as they are maintained and in which the rationalization of the construction, the shortening of the term of works and the reduction of a construction cost are attained by utilizing a building frame or the like after the construction while the building frame and a horizontal supporting member or the like are installed easily and firmly and the strong structure can be maintained for a prolonged term in a sufficient consideration of vibrations and an impulse. SOLUTION: A temporary receiving girder 32 is laid in the construction region of the underground structure just under the ground structure 1. The building frames 8a and 8b supporting the horizontal supporting member 29 of the underground structure 2 are arranged on both sides of the ground structure 1. The building frames 8a and 8b are supported to the girder 32 in the method for constructing the underground structure. Grounds on one side or both side sections of the structure 1 are excavated up to places just under at least a part of the member 29. The end sections of the member 29 are supported on the building frames 8a and 8b inserted just under the member 29 through excavated holes 35. COPYRIGHT: (C)2004,JPO&NCIPI
