摘　　要：针对深部大断面硐室围岩变形严重、支护难度大等问题,以+450 m胶带巷机电硐室为研究对象,提出采用锚注支护方案控制围岩变形并进行工程应用。机电硐室通过注浆提高围岩承载能力以及锚杆索与围岩的耦合效果,通过锚杆索高强支护给围岩较大的支护作用力。依据现场条件制定锚注支护技术方案,现场应用后,+450 m胶带巷机电硐室顶底板、两帮变形量分别控制在41、52 mm以内,表明现场采用的锚注支护方案有效控制了深部大断面硐室围岩变形,能够确保硐室围岩稳定。In response to the serious deformation of surrounding rock and the difficulty of support in deep large section tunnels,taking+450 m belt roadway electromechanical chamber as the research object,an anchor grouting support scheme was proposed to control the deformation of surrounding rock and apply it in engineering.The electromechanical chamber improved the bearing capacity of the surrounding rock and enhanced the coupling effect between the anchor cable and the surrounding rock through grouting.The high-strength support of the anchor cable provided greater support force to the surrounding rock.The technical scheme for anchor grouting support was developed based on the site conditions.After on-site application,the deformation of the roof and floor,as well as the two sides,of the+450 m belt roadway electromechanical chamber controlled within 41 mm and 52 mm respectively,indicating that the anchor grouting support scheme adopted on site effectively controlled the deformation of the surrounding rock of the deep large section chamber and ensured its stability.
