摘要
地应力状态是影响工程稳定性的根本因素之一,也是地下工程设计和施工决策科学化的基础.为了使围岩分类更加科学、合理,根据地应力因素在围岩分类方法中的重要性,提出了包含地应力因素的围岩稳定性判据和应用实测地应力进行围岩分类的方法,并和围岩松动圈分类方法有机结合.结果表明,基于实测地应力的巷道围岩稳定综合分类表科学、简单,依据该表来设计支护参数更为方便、可靠.
The ground stress state is one of the basic factors affecting the stability of underground engineering and is also the basis in the design and construction of underground engineering. According to the importance of ground stress in surrounding rock classification, a new method based on the in-situ measured ground stress and on the stability criterion of surrounding rocks was propoed so as to make the classification more scientific and more reasonable. The combination of this new method with the surrounding rock loose circle method makes the classification more scientific, more applicable, and simpler.
