摘要
秦山核电二期扩建工程3#、4#机组负挖工程距正在运行的1#、2#机组距离为350 m,在核岛负挖过程中,需要控制的条件很多,但是核电环廊的爆破开挖是爆破施工过程中的技术难点和攻关点,文中详细介绍了秦山二期扩建工程3#、4#机组环廊爆破开挖的成功经验。
The distance from 3# .4# machine base excavation of QINSHAN 2 nd phase extension engineering to 1# .2# working machine base is about 350 m, many conditions must be controlled in the opening excavation engineering,especially the circle blasting excavation of the nuclear react building. In this paper, the successful experiences of the circle blasting excavation of 3# .4# machine base excavation project of QINSHAN 2 nd phase extension nuclear react building were introduced in detail.
