石灰岩各向异性膨胀的影响因素研究
|
摘要
对高温过程中双向约束条件下石灰岩膨胀应力的各向异性及其影响因素进行了研究。试验表明,石灰岩试件两个方向上的膨胀应力呈现一定的各向异性,但是各向异性系数并非常数,在500℃时两个方向的膨胀应力相对值差异最大,导热系数、导温系数和膨胀系数是影响石灰岩各向异性膨胀的主要因素。
The author studied the influence factors for the anisotropy of swelling stress of limestone under bidirectional restraints and high temperature.The results showed that the swelling stressses in both directions were anisotropic at some extent. But the anisotropy coefficient was not constant. The difference of the swelling stressses in both directions was the biggest at 500℃. The anisotropy of swelling stress of limestone was mainly influenced by its heat exchange coefficient, conducting temperature coefficient and swelling coefficient.
