摘　　要：软弱破碎围岩的自支护能力是比较弱的,甚至没有自支护能力。在软弱破碎围岩中施工最重要的是提高围岩的自支护能力,以保证开挖及后续作业的进行。提高围岩自支护能力的方法很多,本文着重说明的是坑道稳定性、围岩分级与支护结构之间的相互关系,以及提高围岩自支护能力的基本方法,以突出坑道稳定性、围岩分级与支护结构之间的相互关系在软弱破碎围岩施工中的重要地位。Self-support ability of soil fractured surrounding rock was weaker. To guarantee process of excavation and subsequent, improving self-support ability of surrounding rock in soil fractured surrounding rock construction was more important. Although improving self-support ability of surrounding rock had more method, the relationship of foundation stability, surrounding rock classification and support structure and the basic method of improving surrounding rock self-support ability o were mainly explained in this paper. Then an important role of relationship of foundation stability, surrounding rock classification and support structure was outstanding.
