摘要

特大型地下厂房顶拱层开挖和爆破震动控制,与整个工程项目的工期、成本及施工安全密切相关,因此一直是地下厂房系统工程项目施工的关键。本文介绍了在高地应力复杂地质条件下,为防止岩爆灾害,瀑布沟水电站特大厂房顶拱层开挖工程中,制定了科学合理的施工程序和方法,并在重要特征部位进行了大量的爆破震动观测,总结、掌握了爆破质点振动的衰减规律,为指导整体工程顺利施工发挥了重要作用。此施工经验可供类似工程项目借鉴。
The excavation of the top heading of oversize underground plant and the control of blasting vibration are closely related to cost,project schedule and construction safety,and as a result,they are the most important working procedures in the construction of underground engineering system.The present paper introduced the scientific reasonable construction procedures and methods which were adopted in the excavation for preventing from harm of rock burst under high geology stress and complicated conditions together with the large amount of work done on the survey of blasting vibration at special sections.The attenuation law of particle vibrating was acquired and summarized,which taken an important role in supervising the whole engineering's smoothly going.The experiences are of reference value to other similar projects.
