【摘要】 该项研究在综述软岩支护技术发展历程的基础上,分析国内部分软岩支护技术力学原理,提出首先通过锚索加强围岩自稳能力以控制围岩边形,再采用高阻可缩U型钢支架支护,发挥支架的承载能力并采用壁后充填技术,改善支护围岩相互作用关系,以提高结构承载能力的理论,并将理论结果应用于工程实践。更多还原

【Abstract】 On the base of the development of supporting and protecting technics to too soft rocks,having analyzid some of the supporting and portecting technics in our contry,a theory comes into being,that first streng then the around rocks, stead by using anchor cable so as to control the around rocks,shape,then use U-shaped high-resistanced contractable steel stand to support and protect,make full use of the steel stand while use the filling technice behind wall to improve the around rocks, relationships one another so to make the structure prop up better, then put the theory into project practice.更多还原
