【摘    要】：為了解決隧道爆破開挖成洞過程中爆破荷載對隧址區(qū)邊坡穩(wěn)定性的影響，基于數(shù)值模擬方法對某工程邊坡僅在重力荷載下的穩(wěn)定性作出初判，進而分別對炸藥量100、10、1 kg爆破時邊坡穩(wěn)定性進行了分析，認為在爆破施工中需關注坡腳位移，以防止坡體結構失穩(wěn)。

【關鍵詞】：爆破施工；邊坡穩(wěn)定性；隧道

【Abstract】：In order to solve the influence of blasting load on the slope stability of tunnel site in the process of tunnel blasting excavation， the stability of a project slope only under gravity load is preliminarily judged based on numerical simulation method， and then the slope stability of blasting with explosive quantities of 100， 10 and 1 kg is analyzed respectively. It is considered that the displacement of slope foot should be paid attention to in blasting construction to prevent the instability of slope body structure.

【Key words】：slope engineering; blasting construction; slope stability; tunnel
