岩土材料,即,土、冻土、岩石以及混凝土具有明显的徐变和应力松弛现象。通过徐变试验可容易确定徐变柔量;而应力松弛试验难度很大,故难以通过试验确定其松弛模量,以致岩土材料的松弛模量一直没有合适方法来确定。作者直接根据岩土材料的徐变柔量,通过解析计算给出了其松弛模量的显式算式,并且给出了三个解析算例。
Geomaterials
that are soil
frozen soil
rock and concrete present obviously the phenomena of creep and stress relaxation. By means of the creep tests
their creep compliances can be determined easily. Their relaxation moduli can’t be determined
because it is difficult to do relaxation tests of stress. So till now
there is no a suitable method to determine their relaxation moduli. In this paper
the relaxation moduli of geomaterials are calculated analytically
according to their creep compliances. And three andlytical examples are given.
