哲蚌寺现存内转经道壁画是西藏地区大量壁画中非常珍贵的明代壁画,然而由于藏式建筑结构特点、气候环境、水文地质环境、人为活动等多重因素的作用,建筑地基发生不均匀沉降引起了墙体严重变形,导致了依附其上的壁画出现地仗层空鼓、错位、开裂及脱落等病害,危及到壁画的长期稳定存在。以文物保护基本原则为指导,通过对空鼓错位严重的壁画采取揭取、揭取后修复及墙体维修、原位回贴等保护方法,从根本上解决了壁画支撑墙体稳定性问题,并使壁画变形、错位得到校正,地仗层与墙体之间的空鼓病害得以治理,壁画稳定性显著提升。
However, due to the structural characteristics of Tibetan architecture, climate and environment, hydrogeological environment, human activities and other multiple factors, there is uneven settlement of the foundations of buildings Caused a serious deformation of the wall, leading to the murals attached to the murals on the hollow, dislocation, cracking and fall off and other diseases, endangering the long-term stability of murals exist. Guided by the basic principles of cultural relics protection, this paper resolves the problem of the stability of mural supporting walls fundamentally through the protection of the frescoes, And the deformation of the murals, dislocation be corrected, battlefield layer and hollow wall of the disease can be cured, murals significantly improve the stability.
