【摘要】 在地下工程隧道、地铁、矿山巷道支护中因支护强度低而引发人身事故、造成财产损失,或支护强度过剩造成支护成本过高等现象均有存在,在巷道支护设计和施工中,寻求"临界支护强度",实现安全经济是十分重要的研究课题。对支护原理、临界支护强度的概念、方法进行了探讨,并对影响巷道稳定的方法提出了对策。更多还原

【Abstract】 In the underground engineering tunnel, tunnel, subway and mine tunnel Supporting, personal accidents and property losses are caused because of low supporting strength, so in thedesign and construction of roadway supporting, to seek "critical supporting strength", to achieve safe economy is a very important research topic. In this paper, the principle of supporting and the concept and method of the critical supporting strength were discussed. In addition,the countermeasures for influencing the stability of roadway were put forward.更多还原
