Abstract:The stress-strain behaviors of marble taken from F8 fault-age zone of Luohu Jiancheng district in Shenzhen under the action of temperature from normal temperature(20 ℃) to high temperature of 800℃ and cycle temperature of 100 ℃ to 700 ℃ (repeated 8~9 times) have been investigated by hydraulic pressure servo rigidity rock mechanics experiment system MTS815.03. Influences of the high temperature and high circle temperature on peak strength,post-peak characteristics,deformation characteristics are analyzed and compared systematically. It is shown that the elastic modulus and strength decrease when the samples suffer high temperature,at the same time the strain increases when the peak strength appears;the sample which suffers temperature lower than 400 ℃ generally have the characteristics of brittle failure and the sample which suffers temperature higher than 400 ℃ have the characteristics of plastic collapse,and gradually the peak strength appears unclearly. Comparing the two kinds of experimentation,a conclusion can be drawn that the marble peak strength and elastic modulus under the action of circle temperature are lower than those under the action of corresponding temperature one time and the higher the temperature is,the more obviously the strength decrease and the characteristics of plastic collapse appears.
