南疆地区保温板处治的硫酸盐渍土路基温度变化监测与分析
Analyze and Monitor Temperature Variation of Sulphate Saline Soil Subgrade Treated by Insulation Board in Sourthern Xinjiang
摘要
Abstract
Rigid extruded polystyrene foam boards for thermal insulation(XPS) had been widely applied in permafrost regions, but the applied research of thermal insulation materials applied in saline soil was relatively less.To solve the problems of road damage produced sulphate saline soil subgrade salt expansion from temperature variation with the seasons, built the test sections of sulphate saline soil subgrade treated by insulation boards based on the engineering of Hong Qiao road extension project.Monitor temperature of test section for a lone time in order to know ulteriorly the insulation effect of insulation boards for subgrade.Results showed that insulation boards had rather good insulation effect in the worst season of winter.The temperature of road bed and layer structer was higher than ordinary sections, and greater than 0 ℃.The insulation boards subgrade could prevent subgrade from salt expansion to a certain degree.Finally analyzed the relationship between temperature and depth of test sections subgrade by the method of mathematical statistics in different seasons, and set up the mathematical model.This provided a scientific basis by further using of insulation boards to treat sulphate saline soil subgrade.关键词
