【摘要】：通过对乐山麻浩崖墓的病害及现状勘察、岩样物理力学性能检测、岩样薄片鉴定、矿物成分分析、苔藓植物分离鉴定、室内模拟实验,探讨了崖墓岩石内部因素和各种外部环境因素对其风化作用的机理。得出岩石结构特性是决定崖墓石刻风化的内在决定因素,而水害、可溶盐、酸雨及温湿度交替变化等外界因素则是影响崖墓石刻风化的主要外因,它们在一定条件下相互促进,共同发挥作用,促使其产生酥碱、粉化、龟裂起翘、表面泛盐、片状剥落及表面溶蚀等风化病害。麻浩崖墓石刻风化机理的研究,为对其科学保护提供了理论依据。
[Abstract]:Through the investigation of the disease and present situation of Mahaoya Tomb in Leshan, the physical and mechanical properties of rock sample, the identification of rock sample sheet, the analysis of mineral composition, the identification of bryophytes, the laboratory simulation experiment, The mechanism of weathering caused by internal factors and various external environmental factors of cliff tomb is discussed. It is concluded that the characteristics of rock structure are the internal determinants of weathering of cliff tomb stone carvings, while the external factors, such as water damage, soluble salt, acid rain and alternate changes of temperature and humidity, are the main external factors affecting weathering of cliff tomb stone carvings, and they promote each other under certain conditions. The common function is to cause the weathering diseases such as caustic soda, powdering, cracking and warping, surface salt flooding, flake exfoliation and surface dissolution. The study of weathering mechanism of mahao cliff tomb provides a theoretical basis for its scientific protection.
