摘要

PURPOSE: A construction method of an underground structure, capable of continuously constructing one surface of an underground outer wall using an embedded steel waling and a slab diaphragm effect is provided to cost-efficiently construct an underground structure and to improve construction quality.;CONSTITUTION: A construction method of an underground structure, capable of continuously constructing one surface of an underground outer wall using an embedded steel waling and a slab diaphragm effect, is as follows. A temporary earth retaining wall is installed in the ground. Steel columns are vertically installed in the ground. Foundation parts are formed in the bottom ends of the steel columns. An excavation work is performed in the inner side of the temporary earth retaining wall. Steel brackets are installed in the side surfaces of the exposed temporary earth retaining wall.;COPYRIGHT KIPO 2011
