摘　　要：岩爆灾害严重威胁着施工人员及设备的安全,影响施工进度,已经成为硬岩隧道勘测设计及施工组织中必须考虑的重要问题之一。到目前为止,岩爆控制领域已取得了若干重要进展,但这些进展主要是建立在岩石静力学理论基础之上的,据此提出的大部分措施的控制效果还不甚理想,与从根本上控制岩爆还有较大距离。完整硬脆性岩体、较高地应力和一次或多次动力干扰应该是岩爆发生的3个必要条件,岩爆控制应综合考虑动-静应力的耦合效应。基于动-静应力耦合的岩爆控制已经引起部分学者的关注并已取得一定进展,但还缺乏深入研究。开展基于动-静应力耦合的深埋长大隧洞岩爆灾害控制研究具有重要的理论意义和实用价值。Rock burst seriously threatens the safety of construction personnel and equipments and also influences the construction progress. It already becomes one of the principal problems that must be considered in the designing of hard rock tunnel survey and construction organization. Up to now, rock burst control field has achieved several significant progresses which are based on rock static mechanics, but the control effect is not as ideal as expected. The intact hard brittle rock mass, high in - situ stress, and one or multiple dynamic interference should be three essential conditions for rock bursting. So coupling static stress with dynamic load must be comprehensively considered in rock burst control. Control of rock burst based on coupling static stress with dynamic load has attracted some scholar＇s attention and gotten some progress, but further research is required. Therefore, the study of rock burst control for long tunnels with a big overburden based on coupling static stress with dynamic load is not only of great practical significance, but also of an extensive theoretical value.
