Estimation of Reinforced Railway Roadbed by Geosynthetics on Frost and Bearing Capacity
토목섬유로 보강된 철도노반의 동상 및 지지력 평가
Abstract
Geosynthetics have been studied especially Korean Railway earth works from the outset and have proved successful in both technical and economic terms. Hitherto Geosynthetics have been given consideration chiefly in dimensioning the requisite track subbase thickness, but have not been considered when calculating the thickness of the frost protection layer. this often made it impossible to reduce the thickness of the subbase. The article therefore puts forward a proposal for considering the German Geosynthetics in dimensioning the requisite thickness of the frost protection layer.
Keywords
