| 摘 要： | 根据顺层岩质边坡爆破开挖后产生层裂和后裂的特点,提出了在顺层岩质边坡附近爆破时的边坡稳定系数计算方法,并以渝怀铁路顺层边坡岩体的实测数据为基础,进行爆破地震作用下顺层岩质边坡的稳定性分析。计算结果表明,爆破作用导致边坡自稳能力降低,其降低幅度达54%,据此提出了顺层边坡岩体的爆破开挖方法以及相应的防护措施。为顺层岩质边坡爆破的优化设计提供了理论依据。 |
| 关 键 词： | 爆破振动 顺层岩质边坡 层裂 边坡稳定 安全系数 |

| Abstract: | n view of bedding cracks and back cracks caused by blasting excavation in bedding rock slope,this paper puts forward the calculation method of stability coefficient of bedding rock slope formed by blasting.Based on the measured data of bedding rock slope of Yu-Huai railway,the stability analysis of the slope influenced by blast effect is made,and the calculation shows that blast effect decreased the self-stability of slope and the decrement is up to 54%.Then some blasting excavation and protection methods for bedding rock slope are put forward.This provides theoretical basis for the optimization design of blasting excavation of bedding rock slope. |
| Keywords: | Blasting vibration Bedding rock slope Bedding crack Slope stability |
