中文摘要:
      万安禅院常年受到雨水冲刷、温差变化等风化作用的侵蚀,为消除石窟附近危岩体对参观游客生命安全的威胁,需要对石窟附近的危岩体实施锚杆支护工程。本文以万安禅院石窟文物加固工程为例,采用贡献率法进行加固工程与锚杆施工的相关性分析,通过对石窟地区岩样的强度、成分以及孔隙结构进行分析研究岩石风化程度对其力学性质的影响,并以岩石风化程度、锚杆钻进振动速度、锚孔与洞窟的距离为影响因素,定量统计分析这三种因素对洞窟文物稳定性的贡献率。结果表明:岩石风化程度、锚杆钻进振动速度、锚孔与洞窟的距离的贡献率分别为44.5%、33.33%、22.17%;最大水平振动速度0.098 mm/s符合国家文物保护的三向容许振动速度标准值0.10 mm/s,表明石窟文物在锚杆施工过程中处于安全稳定状态。研究结果可有效减小在修护加固过程中对文物的破坏,并对后面相关的文物加固工程中有一定的指导意义。
英文摘要:
      Wan'an Temple is constantly eroded by weathering such as rain erosion and temperature difference. In order to eliminate the threat to the life and safety of visitors to the grotto, the anchor rock support project needs to be implemented on the rock surrounding the grotto. Taking Wan’an Temple Grottoes Reinforcement Project as an example, the contribution rate method was used to analyze the correlation between reinforcement project and anchor construction. The influence of rock weathering on its mechanical properties was analyzed by analyzing the strength, composition and pore structure of rock samples in the grotto area. The contribution of these three factors to the stability of the cave cultural relics is quantitatively analyzed. The results show that the contribution rates of weathering degree of rock, vibration speed of anchor rod drilling, and distance between anchor hole and cave respectively are 44.5%, 33.33%, and 22.17%. The maximum horizontal vibration speed of 0.098mm/s meets the standard three-way allowable vibration speed of 0.10 mm/s for national cultural relics protection, indicating that the cave cultural relics are in a safe and stable state during the construction of the anchor rod. The research results can effectively reduce the damage to cultural relics during the repair and reinforcement process, and have certain guiding significance for the related cultural relic reinforcement projects.
