Research On Application Of Soil Nailing Anchor Slope Protection In Roadbed In Season Frozen Zone

Soil nailing protection was first used in the foundation pit,tunnel.Then it is applied to the treatment of highway slope.Research for highway slope soil nailing protection in the northeast seasonal frost region is little.Therefore,this paper based on the Jiutai to Shuangyang segment Changchun Economic Circle Highway,study on the protection of soil nailing,to find out the protective form of suitable geographical environment in the northeast.Due to the progress of the project,not yet built in test section.Therefore,in this paper,with the help of geotechnical engineering software FLAC3 D to simulate and analyze.This paper first analyzes the causes of the disease.Then the slope stability analysis of the traditional methods are compared.Finally,decide to use the FLAC3 D to simulate several projects,based on the analysis of the simulation results,to determine the feasibility of the scheme.Further combining with the actual geological conditions of the Jiutai to Shuangyang segment Changchun Economic Circle Highway. Discussion on the construction of the scheme is suitable for Expressway.If not appropriate,discuss the improvement scheme,based on the above work,and ultimately to provide reference for the engineering construction.In this paper,the measures and suggestions in the process of construction are discussed.Including the construction sequence,technical control points of each procedure,material parameter,control method in construction process,and should pay attention to aspects and so on.Finally,through the simulation results and suggestions for construction,put forward the reference opinions for the Circle Highway.
