초록

In this study, a full-scale test was conducted to analyze the behavior characteristics which are related to roadbed according to steel pipe press-in excavation during construction of underground railway crossing. the value of depth of soil cover that is the most sensitive element gets to increase gradually by 1.0, 1.5, and 2.0(H/D). Then we performed press-in excavation and measured the displacements of roadbed with LVDT. When the depth of soil cover level is 1.0(H/D), the maximum value of 5.2mm were seen at the point of 2mm for pipe press. Also, when depth of soil cover had increased, Uplift decreased more than 3 times in comparison with the one.
