Stability Analysis And Treatment Of Cutting High Slope Of Jiangxi Expressway

In the long-term theoretical research and practical construction process of highway construction,it is found that most of the highway sections prone to construction problems are concentrated in the construction of highway in Hilly areas.The stability of highway high slope was the most condition of smooth highway construction.Despite a long time of theoretical research and time accumulation,the variety of hilly landforms in China makes it difficult to find a completely suitable method for highway slope stabilization.According to the record of data and the discovery in practice,it can be known that various kinds of high slope support can form reasonable combination to achieve better effect of long-term stable support and short-term protection.The content of this paper is to find the reasonable protection and support form of high slope in the beautiful,economical and applicable condition.This paper carries out the following research based on the construction project of Changfeng Expressway:1.Collect and classify the types of geological slopes along Changfeng Highway,and mainly investigates the geological topography of high slopes,also analyzes and summarizes the characteristics,types and distribution of this type of high slopes.2.According to the previous investigation and known model data,confirm the influence of seepage pressure on slope and calculate the sliding force that seepage pressure can destroy slope.Establish a reasonable mechanical model and deduce the formula to try to find out the relationship between the parameters of the slope and reveals its internal law.3.According to laboratory data,the field tests is carried out on actual projects in order to calculate how to carry out different support and protection measures for different slopes and to track and test the protection effect of slope protection measures.
