GEOTRACK 을 이용한 유도상 궤도용 아스팔트노반 단면 최적두께 산정

초록

In Italy, Japan, and etc., the asphalt roadbed is specified in the design standard and is widely applied. The advantage of asphalt roadbed can get the strength degradation of the roadbed part due to the anti-penetration effect of the rainwater and softening preventing effect, roadbed thinning effect because of the distribution of the train load, and maintenance expense saving effect by the roadbed frostbite prevention and in-phase prevention. Seen by considering such advantages in the domestic asphalt roadbed should be introduced. In this study, behavior analysis through numerical analysis of a high-speed rail GEOTRACK program that can be reinforced roadbed conditions corresponding to the asphalt roadbed strengthening roadbed were calculated optimum thickness optimal thickness from the depth of the settlement and the state of compared and analyzed.
