| 摘 要： | 为了研究高温环境下岩体锚固机理,通过高温采场三维温度模型ANSYS分析,提出了高温环境下注浆长锚索加固岩体的复合作用锚固理论--"膨胀抬升锚索树根筋混凝土拱理论",简称"胀锚拱理论".该理论克服了目前各种单方面锚固理论的不足,综合形象地解释了高温环境下岩体锚固机理.研究成果为深井开采、有矿石自燃发火危险的矿山开采提供科学决策的依据及有益的参考,对在高温环境下或可能遭受高温影响的边坡、隧道、硐室和采场等岩体加固工程的设计和施工有着重要的参考价值.

| Abstract: | In order to make research on rock anchoring mechanism in high-temperature environment,a comprehensive rock anchoring theory of grouted cable bolts in high-temperature environment,i.e.theory of swelling-rising concrete arch with tree-root-shaped cable bolt reinforcement,is presented by means of ANSYS analysis of 3D temperature models of high-temperature mine stopes.Having overcame the deficiency of every single anchoring theory which considers only a single effect,the paper expounds briefly and explicitly th... |
