摘　　要：通过对特殊条件下巷道常用加强支护方法优缺点分析,吸收优点,改进缺点,提出适应特殊条件巷道加强支护新方法,即锚索棚式加强支护方法。通过建立力学模型和结构分析,论证了其机理的正确性,并经实践应用,证实了其适应性和有益效果。不仅解决了实际问题,其构建的微观狭义棚式小结构、宏观广义棚式大结构力学模型,提出的斜拉锚索观点,倡导的主动被动支护合二为一以及传统索梁支护和棚式支护融为一体的理念,对特殊条件下巷道支护的理论和实践有一定价值和借鉴意义。Through the analysis of the advantages and shortcomings of the common methods of reinforcing support of roadway under special conditions,its advantages are absorbed,and its shortcomings are improved,the new method of reinforcing support of roadway adapting to special conditions is proposed,which is anchor cable-shed reinforcing support method.Its correctness is demonstrated through the establishment of mechanical model and the structural analysis,and its adaptability and beneficial effect are proved by practical application.Not only it solves the problems in the field,but also it constructs the mechanical model of micro-narrow shed small structure and macrobroad shed large structure,and puts forward the viewpoint of cable-stayed anchor,and proposes the idea of combining active support with passive support and the idea of combining anchor cable with shed support,all above are of certain reference significance to the theory and the practice of roadway support under special conditions.
