freezing and thawing cycle meaning in Chinese
冻融循环
冻融周期
Examples
- The result shows that the strength of rock evidently reduces with the increase of number of freezing and thawing cycle
此外也分析了岩石边坡侵蚀过程的机理及影响因素，随着冻融次数的增加，岩石的抗压强度显著降低。 - In cold areas , concrete is always deteriorated by freezing and thawing cycle . the durability and the corrosion of concrete are directly affected by the water - saturated degree of concrete
寒冷地区冻融循环破坏往往是导致混凝土劣化的主要原因,而混凝土内部的水饱和程度又直接影响了混凝土本身的抗冻性和耐腐蚀性。 - By using the method of orthogonal table , the water binder ratio , air content and mineral admixtures which affect the saturation degree are analyzed in this paper . meanwhile in freezing and thawing cycle circumstance including water environment and 3 . 5 % nacl liquor , the saturation degree and the saturation rate are also analyzed . moisture content of the concrete is different by varying water pressure
本文采用正交分析方法,研究了自然饱水和压力饱水条件下水胶比、含气量和掺合料三个因素对混凝土饱和系数的影响规律,并研究了混凝土在纯水和3 . 5 % nacl溶液中受冻后饱和系数的变化规律。 - 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。
