Research on Treatment Measures for Slope Collapse of a Expressway in the Mountainous Area of Northern Guangdong Province
The reasons for the slope collapse of a highway cut in the mountainous area of northern Guangdong were analyzed from the aspects of geological lithology,heavy rainfall,drainage facilities,etc.Based on the geological survey results,stability analysis will be conducted,and three permanent treatment plans will be preliminarily formulated according to the overall principles of cutting and reducing loads,strengthening waist and feet,and strengthening drainage.Comparisons will be made from the aspects of construction risk,construction period,structural durability,and engineering cost.Finally,a first level wide platform scheme was proposed,combined with comprehensive measures such as anti-skid piles,retaining walls,anchor rod grid beam grass protection,and interception and drainage design,to achieve the goal of landslide control.
