冻融条件下混凝土损伤演变与强度相关性研究

At the same time, making the impacting and penetration test for asphalt mixture specimens which have been in the different freeze-thaw cycles, to get the relationship of average penetration depth and fracture tensile strength.

同时，通过对受到不同冻融循环的沥青混合料试件进行冲击贯入试验，得到均贯入深度与劈裂抗拉强度的关系。

Flow rate which is the dominant factor, followed by the freeze-thaw temperature, moisture content, thaw depth and the number of freeze-thaw cycles.

其中流量是主导因子，其次是冻融温差、解冻深度、含水率，再者是冻融循环次数。

To prevent damage from repeated freeze-thaw cycles, the bottom of the foundation must be Below the frost line.

为了防止反复冰冻解冻循环的损害，地基的底部必须在霜线以下（此处的土壤不受地表冰冻的影响）。

Based on test, the article has analyzed the influence of freeze-thaw cycles to concrete compressive strength, flexural strength and cleavage strength, then approached mechanism of fracture by freeze-thaw on micro-structure.

通过试验分析了冻融循环对混凝土抗压、抗折、劈拉强度的影响，并从微观结构探讨了混凝土冻融破坏机理。
