STUDY ON MECHANICAL PROPERTIES OF REINFORCED SOIL RETAINING WALLS WITH PREFABRICATE AND CAST-IN-SITU COMBINED PANEL
In order to study the mechanical behavior and deformation characteristics of prefabricated and cast-in-place composite panel reinforced earth retaining walls under traffic loads,based on the double track retaining wall project of the Chengdu Kunming railway,a composite reinforced earth retaining wall structure of a section of the Chengdu Kunming Railway was taken as the research object.Through on-site measurement and numerical simulation,the mechanical characteristics of the reinforced earth retaining wall were studied,with a focus on analyzing the distribution patterns of panel deformation,soil pressure behind the wall,foundation and wall top settlement.The analysis results indicate that in actual engineering,the number of reinforcement strips in the middle of the retaining wall should be appropriately increased,the spacing between reinforcement bars should be reduced,and the length of reinforcement bars should be increased.The use of alternating short and long reinforcement bars can fully leverage the reinforcement effect of the reinforcement material to strengthen the overall stability of the retaining wall.
