摘　　要：冻土爆破广泛应用于人工冻结的竖井和隧道掘进、极地采矿、极地城市扩建中。目前 ,正在建设的青藏铁路格拉段 ,遇到了大量冻土 ,并在冻土中爆破开挖隧道和路堑。结合青藏铁路的施工和国内外文献 ,综述了冻土爆破的国内外进展情况 。frozen soil blasting is widely used in excavation of shaft and tunnel frozen by using manual works, mining in polar region, and building of cities in polar region. Now, Qinghai Tibet railway is being built, the tunnel and cut excavation in frozen soil need blasting. Based on construction of Qinghai Tibet railway and literatures in home and abroad, the frozen soil blasting advanced research progress is summarized, and the direction of further research is put forward.
