摘要:
通过1:10 比例的直柱基础模型试验，对比测定了不同地温和不同含水率的粉质黏土中普通基础与玻璃钢套筒基础的单位切向冻胀力，研究了玻璃钢套筒在不同粉质黏土地质环境中对切向冻胀力的消减作用效率．研究结果表明，采用玻璃钢套筒后对冻土地基冻拔作用有明显的削弱，玻璃钢套筒切向冻胀力消减系数为0.70~0.83，切向冻胀力消减效率为17.24%~29.70%．土体含水率为20%、25%、30%时，切向冻胀力消减系数平均值分别为0.73、0.74、0.79，切向冻胀力消减效率平均值分别为27.03%、25.60%、20.51%．
Abstract:
Model tests on column foundation were conducted with a scale of 1:10 to determine the unit tangential frost-heave force of column foundation with fiberglass sleeve at different ground temperature and water contentin frozen silty clay. The reduction effect caused by fiberglass sleeve on tangential frost-heave force under different frozen geological conditions were studied as well. Results indicate that the reduction coefficient of tangential frost-heave ranges from 0.70 to 0.83 compared to column foundation without fiberglass sleeve, and the relative reduction efficiency focuse on 17.24% ~ 29.70% depending on the geological conditions.Concretely,reduction coefficients are 0.73, 0.74 and 0.79, respectively, with the water contents of 27.03%, 25.06% and 20.51%.
