高黎贡山隧道位于特定的高地应力和高地热条件下，施工中可能发生岩爆。为了查明高温下隧道硬质岩的物理力学性质，以占隧道硬质围岩绝大部分的花岗岩为代表，进行了高温单轴压缩试验，以期为工程岩爆评价提供较为科学的依据。研究结果表明：从试样应力一应变关系曲线的形状看，主要为Ⅱ型破坏，有发生岩爆的可能。
高黎貢山隧道位于特定的高地應力和高地熱條件下，施工中可能髮生巖爆。為瞭查明高溫下隧道硬質巖的物理力學性質，以佔隧道硬質圍巖絕大部分的花崗巖為代錶，進行瞭高溫單軸壓縮試驗，以期為工程巖爆評價提供較為科學的依據。研究結果錶明：從試樣應力一應變關繫麯線的形狀看，主要為Ⅱ型破壞，有髮生巖爆的可能。

Gaoli Gongshan Tunnel located in the place with specific high stress and high terrestrial heat, so rock burst may occur during construction. In order to identify the physical and mechanical properties of hard rock in the tunnel under high temperature, high-temperature uniaxial compression test was carried out on granite as the representative for hard rock with the purpose to provide scientific evidence for rock burst evaluation. The results showed that II-type failure is the main mode from the shape of stress-strain curve with the possibility of rock burst.
