| 中文摘要:危岩是三峡库区主要地质灾害之一，现呈现出多发、频发的趋势。危岩的分类为坠落式、倾倒式和滑塌式。危岩的综合治理措施有清除、支撑、锚固、拦截、封填、灌浆、排水、防护网等。控爆技术，包括洞室控爆技术、深孔控爆技术、光面爆破、预裂爆破、浅眼循环控爆技术等，以及无声破碎和防护网,均适用于危岩排险工程。危岩的爆破不同于一般的工程爆破，针对不同的危岩类型采用不同的控爆技术和综合应用措施，可以充分保护母岩，稳定岩体，达到应急排险的目的。 |

| Abstract:As a main geological hazard, dangerous rock is multiple and frequent phenomenon in the Three Gorges reservoir area, which is divided into falling, overthrowing and sliding unstable. The comprehensive treatment of dangerous rock includes removal, supporting, anchoring, intercepting, sealing, grouting, seepage and protection network. Controlled blast includes cavern controlled blast, deep hole controlled blast, smooth blast, pre-splitting blast, short hole circulation controlled blast, and soundless breaking and protection network, all suitable to dangerous rock elimination. According to the types of dangerous rock, different controlled blast and comprehensive application measures were adopted to protect patent rock and stabilize the rocks for emergent danger elimination. |
