关于岩体地下工程松动圈问题的思考与探讨
THOUGTHT AND DISCUSSION ON DYNAM-RELAXED RING OF UNDER-GROUND ENGINEERING IN ROCK MASS
-
摘要: 通过对不同教材和专著中岩体松动概念分析,结合松动岩体的研究成果,对岩体地下工程松动圈的形成、特点及影响因素等做了简要探讨,认为松动圈是围岩应力变化大于5%且变化值等于岩体抗拉强度这一范围内的岩体,是松动岩体在岩体地下工程中的一种表现形式。Abstract: Summing up the research conditions at present, the Dynam-relaxed ring of underground engineering in rock mass is qualitatively discussed from its forming, mechanism., characteristics and influencing factors, the definition of dynam-relaxed ring and future research emphasis and direction are also put up.
