摘　　要：研究了高温处理后花岗岩质量、体积、密度、波速以及高温干湿压处理后花岗岩单轴抗压强度的变化规律。结果表明:不同加热温度对花岗岩质量、体积、密度、波速变化的影响程度不同。500℃和300℃分别是干湿压处理下花岗岩抗压强度的阈值,湿压处理会导致花岗岩抗压强度的降低。The quality,volume,density,wave velocity of granite after high temperature treatment and the uniaxia compressive strength of granite after high tem perature dry and wet pressing are studied.The results show that different heating temperatures have different effects on the quality,volume,density,and wave velocity of granite.500°C and 300°C are the threshold values of the compressive strength of granite under dry and wet pressing,respectively,and wet pressing will result in a decrease in the compressive strength of granite.
