| 摘 要： | 从岩爆发生的形式、特征等方面,闸述处于高地应力地区的某水电站长探洞在掘进过程中所发生岩爆问题,并提出对于埋深大、洞径大引水隧洞,由于存在尺寸效应问题,在今后的施工过程中将不可避免地遇到岩爆问题,且发生岩爆的量级将比长探洞要严重,局部洞段可能性发生强烈—极强岩爆,将严重威胁施工设备和作业人员的安全,并制约工程的进展。

| Abstract: | Based on the types and the characters of rock burst,this paper has expatiate the problems of rock burst during the course of construction for a hydroelectric station with high crustal-stress.Because of the size effect,rock burst occur in the processes of construction and will be more serious in long exploration drift.The rock burst in part of the tunnel will even be stronger or super strong, which are very dangerous for the safety of workers and construction equipments as well as the development of the project.This paper has brought forward and dealt with the problems for deep buried long diversion tunnel. |
