摘　　要：为了研究温压炸药在半密闭条件下的爆炸热效应,以WRe5/26热电偶作为效应物,对TNT、TBX-1及TBX-23种炸药在坑道内的爆炸进行了热响应温度测试。试验结果表明:在坑道环境下,温压炸药具有明显的二次燃烧过程,可形成较长的温度作用时间,表现出较大的温度场效应;与等质量的TNT相比,温压炸药爆炸后产生的温度场范围大、温度高、后续持续时间长,对坑道内的人员和设备能产生更大的破坏作用。In order to study the thermal effect of thermal-baric explosive under semi-closed condition, three explosives （TNT, TBX-1 and TBX-2） were tested by using WRe5/26 thermocouple as the analogue in ttmnel. The result shows that the secondary combustion process occurs obviously in tunnel condition. The duration time of temperature was long and the temperature field effect was large. Compared to TNT of the same weight, explosion of thermo-baric explosives experiences bigger field, higher temperature and longer durative time of after-buming. The destructive action was large to human and equipment in tunnel.
