【摘要】：以紅外熱像儀為觀測手段,在室內(nèi)進(jìn)行了自然和飽水狀態(tài)下花崗巖試樣的巷道巖爆模擬試驗,對水環(huán)境效應(yīng)下花崗巖巷道巖爆的紅外輻射特性進(jìn)行了研究。研究發(fā)現(xiàn)飽水試樣巖爆發(fā)生劇烈程度有所減弱,能量釋放速率更為緩慢。水環(huán)境影響下,巖石試樣的紅外三種輻射溫度(平均、最高、最低紅外輻射溫度)具有不同的變化規(guī)律:巖爆過程中,飽水花崗巖AIRT與載荷的關(guān)系更為密切,增溫幅度大于自然試樣。在巖爆發(fā)生時,飽水花崗巖MAIRT升溫幅度小,MIIRT的下降幅度大于自然狀態(tài)下試樣。該研究為地下工程中巖爆紅外輻射預(yù)警技術(shù)提供理論基礎(chǔ)。
[Abstract]:Using infrared thermal imager as observation means, the rock burst simulation tests of granite samples in natural and saturated state were carried out indoors. The infrared radiation characteristics of granite roadway rockburst in water environment were studied. It is found that the intensity of rockburst in saturated samples is weakened and the rate of energy release is slower. Under the influence of water environment, the three infrared radiation temperatures (average, highest and lowest) of rock samples have different variation rules: during the rock burst, the AIRT of saturated granite is more closely related to the load. The range of temperature increase is larger than that of natural sample. At the time of rock burst, the decrease of MAIRT temperature in saturated granite is larger than that in natural state. The research provides a theoretical basis for early warning technology of rock burst infrared radiation in underground engineering.
