【摘要】 机械设备施工所产生的振动对文物的影响问题已越来越引起人们的重视。如何科学合理地判定其影响程度并采取必要的防振对策,进行现场实地测试获取数据是非常必要的。针对莫高窟崖体的特点,对拟采用的锚索加固技术所产生的振动情况进行了分析测试,获得了不同距离处崖体不同方向的振动加速度和速度,较好地反映了该施工工艺引起的振动效应的实际情况,并对其安全性进行了评估,为莫高窟崖体的加固提供了重要依据。更多还原

【Abstract】 Effect of vibration caused by machines on cultural relics is now under severe scrutiny. In order to assess scientifically the effect of the vibration and adopt proper vibration-proofing measure, vibration testing on a site is necessary step. In this paper, based on features of cliff rock, vibration tests are carried out for planned anchor wire reinforcement, and velocity and acceleration records of vibration at different distance from cliff are acquired. The data represent well the actual vibration that could be caused by the working condition of anchor wire reinforcement. Based on analysis of the data, the safety of anchor wire reinforcement on cliff body of Mogao Grotto is evaluated initially.更多还原
