摘要: 根据锚喷支护体系的长期科研成果和黄岛地下水封石洞油库(简称“地下水封洞库”)建设的工程实践,采用喷射混凝土和锚杆加固块状围岩拱的足尺寸模型试验,验证和揭示了锚喷支护的粘结与深入效应对提升围岩自支承力,抑制围岩变形,形成“围岩-锚喷支护”承载体系的显著作用。讨论了大型水封洞库锚喷支护的设计、材料、施工、监测等关键问题。论述了采用与发展低预应力锚杆、钢纤维喷射混凝土、含硅粉喷射混凝土及渗漏水综合控制技术对提高水封洞库的长期稳定性及有效防治地下水渗漏的重要作用。

Abstract: We carried out full-scale model test of applying shotcrete and anchors to strengthen surrounding rock blocks.According to research achievements in this regard and engineering practice at Huangdao water-sealed cavern,we demonstrated and revealed that the anchoring effect could increase the self bearing capacity and restrain the deformation of surrounding rock. We also discussed the key issues inclusive of the design,materials,construction and monitoring of the anchor-shotcrete support for large underground water-sealed cavern. Measures such as applying anchor with low prestress,steel-fiber reinforced shotcrete,shotcrete containing silicon powder,as well as overall control over seepage water could increase the long-term stability of water-sealed cavern and prevent the groundwater seepage.

Key words: underground water-sealed cavern, anchor-shotcrete support system;shotcrete, low-prestressed rockbolt
