Abstract: The high loess subgrade of Baoji-Zhongwei Railway line lied on the filled gully.The height of the loess-filled subgrade was 43 m.The problems of creepage and slippage had occurred two times since the railway line had been in operation.The engineering treatments had been performed,but the problems were not solved.In September 2001,a heavy rain caused again the sliding of the slope.Cracks initiated in the ground on the left side of the railway line and in the slope on the right side of the railway line.The settlements of the railway line and the subgrade reached about 100 mm and 300 mm,respectively.The control of the landslide was introduced,including the research work and the engineering measures.It was shown that the disease was induced by underground water and due to the less compressed filled subgrade.Based on the analysis of the geological boring materials,in-situ investigations and the results of in-situ tests as well as laboratory tests,an integrated scheme for the disease treatment was adopted.The anti-sliding piles were used,the grout reinforcement under the subgrade and the sliding band were performed to increase the density of the soil,and a 3D drainage system was designed to release the underground water.It was shown by the monitoring of the displacement that the slope existed stably after the engineering treatment.The integrated method for prevention of landslides could be used in the similar landslide problem.
