Study On Deformation And Bearing Capacity Characteristics Of Reinforced Embankment Slope

Reinforced soil is joined in soil body strong tensile performance of composite soil of geosynthetic materials. With the rapid development of economy and transportation, The reinforced soil technology will be more and more application in the construction of embankment to improve the bearing capacity of the embankment and control the deformation of embankment.Studying the characteristics of reinforced embankment deformation characteristics and bearing capacity of reinforcement of reinforced soil engineering application and related research has important significance.In this paper, some highway embankment as the prototype, first through the theoretical analysis and calculation of reinforced embankment slope stability coefficient, the influence of different factors on the embankment slope stability are obtained.then uses the indoor model test and the method of three-dimensional numerical simulation study of embankment slope under different conditions of deformation and bearing capacity characteristics and soil additional stress distribution, stress distribution and embankment reinforcement material law of fracture surface morphology characteristics.Through the analysis the following conclusions:(1)Using the proposed theory formula, derived unreinforced, reinforced floor level,two-story three-dimensional stability of reinforced embankment slope coefficient showed a growth, an additional three-dimensional vertical bars in reinforced embankment height also enables edge slope stability factor improved significantly.(2)Through indoor experiment found that reinforcement material layer increases can make increase of ultimate bearing capacity of slope, slope sedimentation reduce,three-dimensional reinforced embankment and the same situation relative to the level of the ultimate bearing capacity of the reinforced embankment has more and more small top settlement, also found that the vertical reinforcement height of three-dimensional reinforced on bearing capacity and settlement of embankment has a significant impact.(3)As the embankment reinforcement material layer increased vertical rib height or three-dimensional reinforcement material will reduce the embankment slope lateraldeformation. Embankment after fracture surface morphology observation experiments found both horizontal reinforcement and three-dimensional reinforced embankment, the fracture surface morphology is different from not reinforced embankment, the fracture surface was rod partition for multiple circular arc surface.(4)under the action of ultimate load of reinforced embankment with the additional stress increased with the increase of reinforcement material layer increases, but under the condition of the same layer distributed three-dimensional reinforced embankment reinforced embankment additional stress is larger than the traditional level.(5)Under the same load increase as reinforced layer on the rod are also decreases, and at the same time close to the road constructed gluten material the rate of change is bigger, the constructed far away from the road surface reinforced material, tensile rate gradually decreases, and gradually gentle curve.(6)through numerical simulation in the slope settlement and reinforcement material force and model test results of mutual authentication, the same as the model test conclusion.The above conclusions can be reinforced embankment slope design and construction to provide the reference and technical support...
