再谈水电工程施工中的岩爆

Rediscussion on rock burst during construction of hydropower project

西南地区水力资源丰富,但该地区地应力很高,洞室施工中岩爆发生频繁,如锦屏二级、溪落渡等工程岩爆现象就比较突出。本文在总结岩爆现象及规律的基础上,依托相关研究成果,就岩爆问题作了深入探讨并提出预防与处理对策,旨在为相关工程抢险提供参考。

The hydropower resources is rich in the Southwest China, however, the ground stress is quite high within the region, and then the rock bursts occur frequently in the constructions of tunnels or caves therein; for instance, the phenomena of rock busts are more prominent during the constructions of the hydropower projects such as Jinping II Hydropower Station, Xiluodu Hydropower Station, etc. Based on the summarization of both the phenomena and the law of rock burst, not only the problems from rock bust are deeply discussed herein, but the relevant countermeasures for the prevention and treatment are also put forward in accordance with the study achievements concemed, so as to provide some references for the relevant engineering emergency risk-elimination.
