【摘要】 花山岩画位于广西壮族自治区宁明县耀达乡,岩画岩石表面受环境因素的作用而风化明显,而且风化类型复杂多样,即有化学风化,也有物理风化,还存在生物风化。本文在岩画保存现状和环境温湿度及风速、风向调查的基础上,结合岩画岩石的XRD分析、偏光显微分析、化学全分析结果,研究了岩画岩石发生物理风化的原因。引起岩画发生物理风化的原因是多方面的,有保存环境中的高湿度、风速风向、光辐射、温差,与岩画岩石自身的物理性质也有关系,其中最主要的因素是高湿度环境。探讨了岩画物理风化病害的治理方法和对修复材料的要求。并依据岩画保存环境特征,研究了治理物理风化的最佳时间。更多还原

【Abstract】 Huashan Rock painting is located at Yaoda town,Ningming county,Guangxi Province.The weathering was obviously on rock surface,including chemical weathering,physical weathering and biological weathering because of bad environment condition.Based on the investigation of preservation condition and surrounding environment condition,the physical weathering was studied.Analyses were also carried out by XRD,polarizing microscopy and bulk petrochemical analysis.Many factors such as humidity,wind,light,temperature fluctuating can influence the physical weathering,but high humidity is the most important one.In this paper,conservation method and requirement for the restoration material also were discussed.According to the character of surrounding environment,the best conservation time was determined.更多还原
