摘要
在自然力的影响下摩崖造像所产生的风化、剥蚀、开裂等种种病害,是与其岩石本体的理化性质有着密切关系。因此,进行摩崖造像保护工程的前期,做好对岩石的工程物理特性调研是非常必要的。为此,根据摩崖造像的分布,经代表性选点、取样并测试。结果表明,四川地区摩崖造像的岩石本体均为砂岩,存在明显软化现象,试验数据有明显的规律性,且各项指标间的相关性较好。其成果为今后保护工程的顺利开展奠定了初步基础。
Damage to the rock cliff figures, such as weathering, denudation, and cracking caused by natural force, are very much related to the rock＇s physical and chemical composition. Therefore, it is important to study and analyze the physical characteristics of rocks before starting a preservation project for the rock cliff figures. Random samples taken from various rock cliff figures in the area have been tested. Results show that the rock is sandstone with a natural tendency for crumbling（softening）. These findings establish a basic foundation to begin protection project on the rock cliff figures.
