Reinforced gabion retaining wall as a new type of retaining structures in thecountry be gradually applied,but on the stability and economy of reinforced gabionretaining wall is still rarely carried out systematic research.Therefore, this thesis rely onthe small wall highway to Pu’er City,Yunnan Province,reinforced gabion retainingwalls alumnus HanDong on the basis of further research. First reinforced gabionstructure of the status quo reviewed and summarized the systematic exposition of thebasic theory of reinforced gabion retaining wall reinforcement mechanism,stabilitycalculation and then,on this basis,plus tendons gabion retaining wall’s stability andeconomy of comprehensive research, reinforced gabion retaining walls and retainingwalls in a simple techno-economic analysis. The main findings are as follows:1、Common size (the length of the cage size and reinforced mesh) reinforcedgabion retaining walls,gabion units to be grouped by different groups of gabion unitreinforced gabion retaining wall builtmode and to analyze its stability,determine thestability of the reinforced gabion retaining wall the size of the gabion unit;2、After a comparison of modeling results to identify the impact of the cage thesize of the gabion unit size and the length of the reinforced mesh reinforced gabionretaining wall stability within a certain range,cageheight and width than the more stablethe smaller reinforced gabion retaining wall, the more stable the longer reinforcedgabion retaining wall of reinforced mesh;3、PLAXIS software to calculate the stability of the retaining wall of reinforcedgabion safety factor, combined with the economics of reinforced gabion retaining wallreinforced gabion retaining wall based on the analytic hierarchy process based on acomprehensiveevaluation to identify the reinforced gabion unit specifications (0.5×1.0×6.0) reinforced gabion retaining wall is relatively stable and more economical;4、Reinforced gabion retaining walls and retaining walls technical economicanalysis,and on this basis with examples further proof reinforced gabion retaining wallsshould be in terms of stability,economic and eco-superior to traditional retaining wall;5、Finally a summary of the full text,pointing out the inadequacies of the presentwork,as well as the need for further research content and direction.
