The third period of Jingcheng freeway(Shayugou-city boundary section of Beijing)
Abstract:Taken the slopes of the third period (Shayugou-city boundary section of Beijing) of Jingcheng freeway as example, this study surveys the forms and characteristics of the landslide, analyzes its reasons and give some control suggestions. Results show that, the forms of slope landslide occurred Slope-instability and Zoarium-decline and Indriection-landslide for both Rock slopes and Soil-rock slopes.Slope-instability was the most important form for the two slope types. By analyzing slope landslide causes,it can be obtained that Drainage Works could give the reason for Slope-instability form, i. e. faultiness on Soil-rock slopes and irrational design on Rock slopes. Stabilization Works could give the reason for the Zoarium-decline form, i. e. insufficient anchoring effect of anchor and limited anchoring effect of plants roots on Soil-rock slopes, vice verse on Rock slopes. The landslide of uphill could give the reason for Indriection-landslide form. In conclusion, some advices about landslide prevention were given according to the existing problems of these landslide slopes from Drainage Works and Stabilization Works and so on.
