复杂地质条件下高边坡爆破控制技术

为降低高边坡开挖过程中的有害效应,以雅砻江两河口水电站工程为例,重点探讨了在复杂地质条件下高边坡爆破控制技术的实践应用。从爆破参数设计、安全距离以及安全防护措施等方面,介绍了复杂地质条件下高边坡爆破过程中采取的施工方法和爆破安全技术,通过对钻爆参数的合理设计以及安全防护的严格要求,使该边坡开挖取得了良好的效果,确保边坡稳定和周围建筑物的安全,为今后类似情况高边坡开挖提供参考。

Control Blasting Technique of High Slope in Complex Geological Conditions

To mitigate the harmful effects during the excavation of high slope,the Lianghekou hydropower station project in Yalong Rive was taken as an example,and the practical application of control blasting technique of high slope with complex geological conditions was discussed. From the blasting parameters,safety distance to security pro-tection,the blasting construction and safety technology in blasting process of high slope with complex geological con-ditions were discussed. The satisfactory excavation effect was achieved by reasonable blasting parameters and strict safety protection. Finally,the slope stability and building security were ensured,which provides reference for the simi-lar engineering.
