Low Compressibility at the Transition Zone of Railway Tracks Reinforced with Cement-Treated Gravel and a Geogrid under Construction
Autor: Seongyong Park, Dae Sang Kim, Ungjin Kim, Sangseom Jeong
Publikováno v: Applied Sciences, Vol 12, Iss 17, p 8861 (2022)
In the transition zone of railway tracks, track irregularities occur frequently due to differential settlement, which arises from the difference between the vertical supporting stiffness of the abutment and the backfill. This is disadvantageous becau

Interlocking Settlement Induced by Widening Subgrade of Railway Line
Autor: Dae Sang Kim, Ungjin Kim, Young Kon Park
Publikováno v: Applied Sciences, Vol 12, Iss 13, p 6638 (2022)
In areas where it is difficult to secure additional land for railways, a plan to increase rail transport capacity by widening existing embankments is required. When widening the embankment, additional stress is generated at the bottom of the existing

Evaluation of Deformation Characteristic of Railway Subgrade Using Reinforced Rigid Walls with Short Reinforcement under Repetitive and Static Loads
Autor: Ungjin Kim, Dae Sang Kim
Publikováno v: Applied Sciences, Vol 11, Iss 8, p 3615 (2021)
A full-scale reinforced subgrade for railways (RSR) was constructed, and repetitive and static load tests were performed to analyze the deformation characteristics of reinforced rigid walls with short reinforcements for railway subgrades that require

Evaluation of Horizontal Subgrade Reaction Modulus for Integral Abutment Based on Changes in Buffering Zone Stiffness
Autor: Dae Sang Kim, Ungjin Kim
Publikováno v: Journal of the Korean Society of Hazard Mitigation. 22:7-13
The buffering zone, which can control the stiffness of the backfill material, is applied at the integral abutment (IA) to reduce the horizontal earth pressure on the abutment and decrease the residual settlement at the transition zone. Numerical anal

Analysis of Behavior Under Horizontal Loads of Integral Abutment for Railways with Buffering Zones
Autor: Ungjin Kim, Dae Sang Kim
Publikováno v: Journal of the Korean Society of Hazard Mitigation. 22:1-6
The integral abutment (IA) with buffering zones is a technology that pre-constructs backfill before abutment construction. It can reduce the maintenance cost owing to the decrease in the residual settlement of the backfill after opening. Furthermore,
