Analysis and Mitigation of Baolongyu Landslide in Chang'an District,Xi'an
This paper presents the case history of Baolongyu landslide in Chang'an District,Xi'an City.The basic characteris-tics of the subsurface conditions at the landslide site,possible factors that might triggering the landslide are evaluated and the stability of the landslide is also performed through the geotechnical data provided by the investigation and the back analysis.The geotechnical parameters required for the landslide mitigation design are obtained and the mitigation plan is therefore pro-posed.The research results show that the Baolongyu landslide is a shallow accumulation landslide induced by the rainfall;The landslide is in an unstable state under the natural conditions.According to the stability of the landslide analysis,the concept of comprehensive mitigation:"slope backfill+sheet pile wall+passive protective wire mesh net+reinforced concrete retaining wall+intercepting and drainage"is finally adopted.The wedge-shaped chute is backfilled,the sheet pile wall and the rein-forced concrete retaining wall are arranged at the toe of the landslide slope,the passive protective wire mesh net is arranged at the top of the pile and the wall,and the chute and drainage ditch are arranged on the slope to drain the rainwater on the slope and to ensure the stability of the landslide.
