摘要
殿堂壁画由于绘制在建筑墙面上,常常因受到地下毛细水及可溶性盐的侵蚀而发生酥碱。四川新津观音寺壁画所在的墙体,底部以石条和原木地做下碱,上部以竹泥墙做墙身,研究发现,这种特殊的墙体结构可有效防止地下毛细水的上升和可溶性盐对壁画的侵蚀。但近年发现壁画下端出现了酥粉病变,墙体含水率及可溶性盐分析结果表明,20世纪70年代垫高了殿外地面并增砌了护墙,这些防护措施正是壁画劣变的诱因。
Murals painted on walls of palaces and halls usually become frail because of the erosion of capillary water and soluble salts.In the Guanyin Temple in Sichuan's Xinjin District,the base of mural walls was built with stone bars and timber bracing beams for the sake of alkali treatment,and the upper part was made of bamboo wattle and daub.Research results show that such a special wall structure could effectively prevent the rise of capillary water from underground and the erosion of murals by soluble salts.However,in recent years,the bottom part of the murals have become frail and flaky.Analyses of the walls moisture content and soluble salt content indicate that the elevation of the ground outside the hall and the building of parapet walls,both of which were protective measures taken in the 197Os,have induced the deterioration of the murals.
