Study On Distribution Law Of Temperature And Humidity Of Construction Waste Embankment In Xi’an To Xianyang Expressway

Construction waste material has been widely used in engineering as a new building material. It is of great significance for the research of engineering properties of construction waste materials. This thesis which is based on the engineering of expressway of Xi’an to Xianyang which select two typical sections to carry out the field test. And analyzed the change law and the influence factors of the temperature and humidity of the construction waste embankment. Putting forward temperature and humidity zoning and temperature field prediction model.To carry out test of the material, analyzed the composition and relative content of construction waste materials.Determination of the content, water absorption, density and other indicators of each component. Analysing the contrast test of the grain size gradation between the original aggregates and after the field rolling aggregates.Do the analysis about the construction waste embankment temperature field data. Obtained the distribution and change rule of the embankment temperature filed. According to the variation of embankment temperature field divided the embankment into different areas.Obtained the change rule of the embankment absorbing and release heat condition. Analysing the effect of southern and northern slopes. Considering varying factors that can influence interior embankment temperature, such as amplitude, hysteresis, horizontal cover depth and vertical cover depth, which can establish a prediction model of the temperature changes.Analyzed the distribution rule of the embankment humidity filed, which shows that the embankment humidity is influenced by the initial humidity content and the toe of the embankment and the central belt separation susceptible to external water intrusion. According to the humidity increment of the embankment,dividing the embankment into different areas.Do the analysis about the water intrusion embankment in different situations and obtaining the affect characteristics and the influence degree, which is the basis for further studing of embankment deformation.Finally, analyzed the two kinds of infiltration modes of the embankment.The variation characteristics of the humidity field of embankment under different infiltration modes are available,and putting forward the corresponding treatment measures.The conclusion provides a reference for further research of the construction waste material.
