摘要： PROBLEM TO BE SOLVED: To provide a construction method for underground passages of two or more basements for shortening a construction period while relieving ground traffic congestion early. SOLUTION: In this construction method, after two rows of earth retaining walls 3 are constructed over a prescribed extension along the extending direction of a road 5, upper stage space holding members 2 are installed near the upper ends of the earth retaining walls 3, and the ground below the upper stage space holding members 2 is excavated down to a prescribed depth. Excavation is advanced from an entrance 11, for instance, to proceed with excavation to a halfway position of construction extension of the first basement passage 1, and when lower stage space holding members 2 are installed down to a completed spot of excavation, excavation of the second basement passage 1 is started from an exit 22 of the second basement passage 1 adjacent to the entrance 11. The construction period of the underground passages of two basements can thereby be shortened. COPYRIGHT: (C)2004,JPO&NCIPI
