根据试验结果，分析了纳米硅粉水泥土的变形特性，并对其应力应变曲线进行了二次抛物线拟合分析，推导了曲线上升段的表达式。 - It was shown that salt expansion value of low liquid - limit clay was accumulated before the sixth freezing and thawing cycles , but the increment of salt expansion was reduced gradually with increasing cycles ; the salt expansion accumulation of low liquid - limit clay could be separated into three phases ; the deformation of clayey sand was mostly frost heave and subsidence under cycles , and collapsibility value of clayey sand was accumulated with increasing cycles ; the variation of salt expansion ratio and collapsibility ratio was a parabolic function of freezing and thawing cycles
试验结果表明：低液限粘土前五次冻融循环过程中盐胀具有较好累加性，随着冻融循环次数的增加，盐胀量增长速度逐渐降低；含砂低液限粘土的盐胀过程可以被分为三个阶段；粘土质砂在冻融循环过程中的变形主要为冻胀和沉降变形，具有较好的溶陷累加性；低液限粘土、含砂低液限粘土的盐胀率和粘土质砂的溶陷率与冻融周期之间的关系符合二次抛物线变化规律。 - The results indicate that the ratio of span to rise , the ratio of reinforcement and the stretching controlling stress are the three primary influencing factors to the failure pattern of the slab . in addition , the relationships between the ratio of deflection to span and the ratio of span to rise and the stretching controlling stress submit to linear curves , the relationship between the ratio of deflection to span and the ratio of reinforcement submits to a quadratic parabola curve
运用数值分析程序计算了175组不同跨高比、配筋率、张拉控制应力的中强( 1270mpa )螺旋肋钢丝预应力空心板，结果表明跨高比、配筋率、张拉控制应力是影响空心板破坏形态的主要因素，且构件挠跨比与跨高比和张拉控制应力呈线性关系，与配筋率呈二次抛物线关系。
