摘要
近年来,敦煌市夏季出现强降雨天气,这种偶发极端天气造成高湿空气通过窟门扩散进入洞窟,增加窟内相对湿度,加速壁画各种病害,对莫高窟文物构成极大威胁。本文基于对莫高窟现场调研和分析,设计了一套莫高窟洞窟环境调控设备系统,通过输送一定物理状态的空气使洞窟内形成正压,防止湿气侵入,维持洞窟内热湿平衡,对莫高窟文物起到应急保护效果。
With the heavy rainfal weather of Dunhuang city in recent years, humid air spread into the cave through the door to increase the relative humidity of the grotto and accelerate al kinds of diseases of the murals. Consequently it could pose a great threat to the cultural relics of mogao grottoes. Based on field investigation and the analysis of the mogao grottoes, a set of environmental control equipment system in the mogao grottoes grottoes would be designed in this paper, which conveys a certain physical state of air to form positive pressure inside the cave. So that the phenomenon of moisture intrusion would be prevented, and the balance of thermal and humidity of the the microenvironment of the caves would be preserved. Accordingly the cultural relics of the mogao grottoes would be protected in the case of urgency.
