Abstract:

High-standard railway routes require great rigidity due to their curvature and curvature limits. Especially in the limit balance conditions in the ancient heyelane (paleo heyelane) areas, the harvests and tensions conditions create imbalance and result in heyelane. Ankara - Istanbul High Speed Train Project (Bilecik Illi Vezirhan District south), after the construction of the shui, the old heyelans located in the ground have been triggered, the mass movement that can be tracked by ondulation on the rails has occurred. In this study, the aim is to determine the cause and the total resistance forces that must be created in order to stop the mass movement that occurs. For this purpose, geological units have been distinguished from land studies, a sliding model has been created using stretching fractures and inclinometer measurement data. In the model created, in the limit balance condition, the mass parameters for the heilan material are determined using the feedback method. Then the resistance force required in the case of non- earthquake and earthquake (0.2 g) for the purpose of stability is calculated by making a limit balance analysis with the "Janbu" method. The results of the studies have found that the heyelane mass covers an area of 500 meters tall and 280 meters wide, its depths range from 10.20 to 49.80 meters and continues to move with a daily drive of 1.5 to 2 mm. The analyses and the stability of the heiland have been found that 450 kN/m in the case of no earthquake and 12500 kN/m in the case of 0.2 g in the case of earthquake. Analysis has concluded that long-term stability is only possible by joint assessment of the load relief, ball filling and resistance structure systems.
