Abstract
As the development of around railway area, the subsurface construction using non-opencut method under the railway has been recently increased. When the structure under railway is constructed, the track support stiffness of the ground is not considered as an important design factor. In this study, laboratory tests were performed to investigate the ground movement characteristics nearby the subsurface structure. Based on the laboratory test results, 3D numerical analyses were performed to find out the dynamic characteristics of the concrete track. The numerical analyses results showed that displacements above the structure were varied with the soil thickness. When soil thickness is 3m, tensile stress of the results was less than allowable tensile stress. However, when the soil thickness are 1m and 2m, concrete tensile stress on the concrete track exceeds the allowable tensile stress.
