石窟岩体稳定性监测系统应用与研究

Research on cave rock stability and application of a monitoring system

石窟岩体不稳定病害是威胁石窟安全的主要问题之一,需实时对石窟类岩体稳定性变化进行监测,获得的大量基础数据,可进一步验证和校核石窟类岩体保护的各种数学模型的有效性、可靠性。本研究以云冈石窟作为研究对象,探索各种监测手段在石窟岩体稳定性分析评价中的应用。成功地引入工程安全监测中的分析方法,研发了石窟岩体稳定性监测数据分析系统,对岩体表面变形、危岩体倾斜及岩体表面温度场分布等与岩体稳定性密切相关的因素进行了探索性应用研究。本研究促进了文物保护与其他专业学科的交叉与融合,加强了我国石窟文物保护的科技支撑能力。

The instability of rock bodies is one of the major threats to the cave relics. Real - time monitoring of rock bodies is needed. If a large amount of data is collected, it can be used to construct a mathematical model to evaluate the effectiveness and reliability of protection plans. Using the Yungang Grottoes as an example, this paper selects monitoring systems based on characteristics of the rock mass and introduces a statistical analysis model used in stability monitoring to analyze and evaluate the stability of rock mass. Research focused on factors closely associ- ated with the rock mass stability, for example, rock surface deformation, dangerously inclined rock masses and rock surface temperature distribution. This research promotes the integration of the study of cultural relic preservation with other disciplines. Also it helps the preservation of cultural rock relics based on science and technology.
