Soil has very weak tensile strength,so materials with a certain tensile strength will be added to the project to improve the certain tensile.and the overall stability and deformation resistance of soil.Geogrid is a widely used reinforcement zaterial.Reinf--orced earth retaining wall has the advantages of convenient construction,economical saving,friendly environment,and strong stability.Widely used in roads,railways and other fields.Theoretical study of reinforced earth retaining wall lags behind practical application.This article has carried out the following research on Integral panel reinforced earth retaining wall based on Integral panel reinforced earth retaining wall engineering characteristics:(1)Introduced the types of reinforced materials and Integral panel reinforced earth retaining wall's structural form.(2)Discussed reinforced soil's function.Enumerates the failure modes of reinforced earth retaining walls.The stability,internal stability and overall stability of the reinforced earth retaining wall were studied.According to domestic regulations,the article briefly explains the internal and external stability analysis of reinforced earth retaining walls subjected to earthquakes.(3)The flexible displacement meter and soil pressure box are embedded in the experimental section of Dong jiakou reinforced earth retaining wall.According to the monitoring data,the engineering characteristics of retaining wall during construction are analyzed.The results show that the soil pressure distribution of the monolithic reinforced earth retaining wall is nonlinear.The vertical earth pressure at the bottom of the wall has a double peak phenomenon.There is a single peak of soil pressure inside the wall.There is a convex belly phenomenon in the lateral earth pressure distribution along the wall,and there is a certain difference between the value and the theoretical value.The tensile reinforcement affects the distribution of soil pressure inside the wall and plays a weakening role.The tensile deformation along the length of reinforcement is nonlinear distribution,and there is a single peak phenomenon.(4)Using numerical simulation software PLAXIS to compare the numerical simulation with the measured values in the construction period.The simulation results agree well with the measured data.The results of the analysis verify the weakening effect of tension reinforcement on soil pressure.By using the dynamic analysis module and input seismic load,the acceleration and lateral deformation rule of monolithic panel reinforced earth retaining wall under ground motion load is analyzed.
