실대형실험을 통한 지하횡단구조물의 지반 거동특성 연구

초록

In this study, Full scale test was conducted to analyze behavioral characteristics acting on the track roadbed with excavation through steel pipe injection, a non-exclusive method of crossing construction under railroad as primary target. Underground Railway Crossing Structures are crossing through railroads and roads has been often constructing without excavation, however the studies on behavior characteristics while constructing as pressed in pipe are not enough relatively. With that reason, we evaluated workability and measured displacement of face based on the existing results of scale test. We compared to the change rates of soil depth with displacement ratio under the condition of an actual formation. According to the experiment, the maximum degree of uplifts was seen while lowering soil depth value, had the case been reversed, an inverse case was seen as well. The case, the diameter and soil depth is the same, is quite effects on uplifts, so considering these analysis, we could draw a conclusion that we need to decrease the degree of uplifts by managing construction to be occurred big pressures by press-in face
