Analysis And Treatment Of Qian-Zhang-Chang Railway Section Landslide

With the rapid economic development in our country,the railway construction in various places is also under planning and implementation.The railway crosses over a large scale,there will be a variety of geological conditions and different environmental factors,the landslide is not only harm to the line itself,also have a certain impact on the surrounding environment of the line.Based on the background of the project of DK281+030~DK281+321 for the new construction of Qian-Zhang-Chang Railway,according to the analysis of the railway and the landslide geology and hydrogeology,construction conditions,environmental factors,combined with literature research and related similar landslide,in-depth analysis of the causes of the landslide.Put forward the idea of controlling the landslide and the concrete implementation method.It provides the ideas of landslide prediction and landslide control for future construction,at the same time it provides reference for other landslide prediction and control.(1)Analysis of the cause of the landslides in DK281 + 030 ~ DK281 + 321 section.The construction conditions,geological conditions and environmental factors of the DK281+030~DK281+321sectionofnew construction of Qian-Zhang-Chang Railway before landslide are analyzed.The new construction of Qian-Zhang-Chang Railway DK281+030 ~ DK281+321 section of landslide soil engineering test.Through the landslide site survey,the comprehensive analysis of the site data and the reference of relevant landslide theory,the causes of the landslides DK281 + 030 ~ DK281 + 321 were determined.(2)Study on the stability of landslides in DK281+030 ~ DK281+321 section.Landslides are monitored both before and after landslides.The critical value of the landslide is studied by monitoring the settlement of the slope.GeoStudio software is applied to establish the numerical analysis model for the landslide of the DK281+030 ~ DK281+321 section of the new construction of Qian-Zhang-Chang Railway.The stability of the landslide is studied under different conditions,and the occurrence of the landslide is forecasted.(3)Treatment of landslides in DK281+030 ~ DK281+321 section.Through the similar landslide literature research,the landslide site monitoring data and the cause of landslide are analyzed.Combined with the landslide site,the governance plan is put forward,which is divided into two aspects: emergency and implementation.In the implementation plan,specific implementation methods such as brush slope,anchor frame beam,anti slide pile,truncation ditch,anchor bar,reinforced concrete mesh and shotcrete slope are put forward.
