多场耦合下岩土质文物风化机理试验装置研究

摘要

岩土质文物的破坏往往是多因素共同作用的结果，开展多场耦合下的岩土质文物病害机理研究对于遗址的保护具有非常重要的意义。多场耦合条件下的环境模拟技术已经广泛应用于科学研究和工业测试领域，具有时间可控性、条件重复性和数据精确性等突出优点。本研究基于其他行业的研究成果，首次研发了基于多场耦合下的石窟围岩风化机理模拟试验系统装置，通过对岩土质文物模拟环境和测试技术的研究，确定了多场耦合实验室的布局、功能、技术性能指标，将为敦煌石窟围岩风化和壁画盐害机理研究乃至全国岩土质文物保护研究提供高技术环境仿真试验平台，提升岩土质文物风化机理和保护材料性能评价的研究水平。%Most damage to rock and earthen relics is caused by the interaction of multiple environmental parameters, making the study of their deterioration mechanisms under multi -field coupling conditions very important. Artificial environment simulating techniques under multi -field coupling conditions have been extensively applied to scientific research and technical tests because of advantages such as time controllability, parameter repeatability, and data accuracy. Based on the multi -field coupling research in other fields, engineering equipment has been developed to study the weathering mechanism of rocks surrounding caves for the first time. By studying simulated environments and testing techniques for rock and earthen relics, the design, function and technical specifications of the equipment have been confirmed. This will provide a high -tech environment simulation platform for studying the weathering mechanism of the surrounding rocks and salt disruption of the wall paintings and evaluation materials of the Dunhuang caves and other rock and earthen relics in China, as well as promote research on the weathering mechanisms and evaluation materials of rock and earthen relics.
