摘要
为了解决隧道爆破开挖成洞过程中爆破荷载对隧址区边坡稳定性的影响,基于数值模拟方法对某工程边坡仅在重力荷载下的稳定性作出初判,进而分别对炸药量100、10、1 kg爆破时边坡稳定性进行了分析,认为在爆破施工中需关注坡脚位移,以防止坡体结构失稳。
In order to solve the influence of blasting load on the slope stability of tunnel site in the process of tunnel blast⁃ing excavation,the stability of a project slope only under gravity load is preliminarily judged based on numeri⁃cal 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 blast⁃ing construction to prevent the instability of slope body structure.
