摘要
According to the present invention, a girder construction method of a room-and-pillar underground structure including a rock pillar (200) and an inner space (100) includes: a first step (S100) of determining a target surface where the girder is to be constructed; a second step (S200) of determining the quantity of the girder to be constructed on the target surface; and a third step (S300) of constructing the girder on the target surface. The first step (S100) includes the steps of: reviewing a stress intensity ratio by shapes of the rock pillar (200) and the inner space (100); reviewing a critical strain ratio by shapes of the rock pillar (200) and the inner space (100); and calculating a space utilization ratio by space utilization purposes of the inner space (100). The girder construction method of the present invention can increase stability and make better use of a space of a room-and-pillar underground structure.;COPYRIGHT KIPO 2016
