Study On Stability Analysis Of Rein-forced Fly Ash High Subgrade Slope

Geogrids with high strength, low deformation, corrosion resistance, and soil andother characteristics of the interaction can be as important or permanent structures touse. Light weight fly ash,has big mutual action with the geosynthetics, as a geotechnicalstructures can reduce the effect of filler on the pile in the foundation load, earth pressureon retaining walls, slope of the gravity stress, while turning waste into wealth, savingconstruction cost, and also avoiding Ecological damage because of exploitation of sandand gravel.Until now studied with the fly ash as the reinforcement soil body’sreinforcement complex structure are relatively few,but the application prospect of flyash waste is quite extensive, especially considering the use of fly ash to build dams,retaining walls more far-reaching significance. In this paper, through the strengthcharacteristics of fly ash in water and fresh water conservation and contact surfacecharacteristic and reinforcement mechanism of geogrids and padding interaction,depends on FLAC which the American TIACSA consultant firm develops groundproject analysis software to study on stability analysis of reinforced fly ash highsubgrade slope. The concrete content includes:(1) Through analysis with water wet strength of the material solidified fly ashformation mechanism, getting their basic mechanical properties and index. Through thedesign of experiments on different ages, cement content and curing conditions curingagent factors affecting the analysis, water wet fly ash cement solidification underdifferent conditions of intensity variation. The results showed that curing water wet flyash cement has good stability and durability, mixing curing mixture strength with age ofstable growth, increased strength by adding cement content. The pilot research on theretaining structure, embankment reinforcement and ground improvement has importantengineering applications such as theory and practice of value.(2) Elaborates the geogrids and the padding interaction contact surface characteristicand the reinforcement mechanism(3) Study on stability analysis of reinforced fly ash high subgrade slope. FLAC3D program introduction and basic theory. Use strength reduction factor method，to analyzethe stability of retaining walls from the height of fly ash wall and the geo-gridrein-forced retain fly ash wall. And carry out a detailed geogrid interface characteristicson the impact of retaining walls. Provide the project for reinforced fly ash high subgradeslopel widespread application.
