The assesment of rockfall analysis near a railroad: a case study at the Kızılinler village of Eskişehir, Turkey

摘要: Rockfalls from basaltic lava flow hills and the rockfall hazard for railroad passing along Kizilinler village (Odunpazari/Eskisehir) were investigated in this study. are detected between 14 + 000 18 + 750 km on Eskisehir-Kutahya railroad. This part of is controlled daily case rockfall, falling blocks cleared by workers. The rapid weathering tuff litology under flows cause rockfalls. As a result unit, basalt rock particles fall discontinuity surfaces due to gravity forces. geology region, properties blocks, length during field During studies, greater than 5 m diameter that had passed other side railroad, recorded. In order define geologic mass joint properties, two scan-line surveys performed study area. A series block simulation studies held with computer program. train was determined. simple regression analysis carried out height, horizontal volume new empirical equations evaluation estimation performances some existing determination runout distance using data also performed. However, prediction performance proposed previous not significant, except derived height rockfall. Rockfall Risk Rating system applied at selected slope sections Consequently, area classified as medium risk. Active passive protective measures suggested
