摘要： 岩锚梁梁体与围岩联合受力体系有效性和长期安全运行取决于岩台成型质量、锚固质量、围岩稳定和梁体结构的完整性。结合地下厂房岩锚梁的施工实践和已建、在建水电工程的施工经验，对岩锚梁施工的关键技术进行了针对性和系统性的研究后，认为有必要在现场开展相关工序的试验，并埋设必要的监测仪器，增加分析手段，同时加大技术管理措施。

Abstract: Rock anchor beam construction requires the knowledge of controlled blasting, rock anchors, concrete and monitoring of surrounding rock deformation. It has been widely applied to underground powerhouses for pumped storage hydropower stations and the canyon hydropower stations. The effectiveness and longterm safe operation of the beam and surrounding rock depends on the integrity of the rock bench molding quality, anchoring quality, stability of the surrounding rock and beam structures. Based on the engineering experience from relevant projects both completed and under construction, the author believes that it is crucial to perform insitu testing, and realtime monitoring of the construction, and increase technology management measures.
