摘要
布达拉宫是一处世界文化遗产,保存了大量的反映西藏政治、经济、文化、社会生活、佛教等题材的壁画,具有极高的历史价值、艺术价值和科学价值。受自然和人为因素的影响,壁画不同程度的产生了空鼓、起甲等病害,严重影响了文物的保存。本文针对壁画的最严重的空鼓病害,通过室内实验和现场试验研究,筛选出了以PS为主剂,粉煤灰(F)加阿嘎土(A)为填料的无机灌浆材料并辅以锚杆补强加固空鼓壁画的修复材料和修复工艺,取得了良好的效果。同时对内窥镜检测壁画空鼓状况以及探地雷达检测空鼓加固后的效果也做了尝试性的试验研究。
As an inscribed world cultural heritage site, the Potala Palace preserves a lot of wall paintings in the themes of Tibetan politics, economy, culture, social activity and Buddhism, possessing great values in history, art and science. Due to natural environment and human factors, the wall paintings are vulnerable to deteriorations including delamination and flaking, which are dangerous to preservation of such cultural heritage. This paper focuses on conservation method for the most serious deterioration of delamination, the conservation material of inorganic grouts made from PS as binder and fly ash in addition of native soil Aga as filler, and the conservation technique of grouting and anchoring are proposed through experiments and in-situ tests. It is proven to be effective to coservation of delaminated wall paintings. Attempts of inspecting the inner condition of delamination by video probe and evaluating the grouting effectiveness by ground penetrating radar are made at the same time.
