摘要
对洛阳龙门石窟围岩风化特征及风化作用影响因素进行调查研究,指出目前围岩风化作用主要为生物风化和物理风化作用,并进一步对其风化机理进行了探讨。以往研究结果认为风化作用主要类型为物理风化作用,本文研究表明,目前由于西山山顶植被的不断发育,随着植被根须机械破坏作用及植被腐殖质分解的产物引起岩体解离的生物化学破坏作用日益加剧,生物风化作用亦已成为风化破坏主要影响因素,应引起有关部门注意。
Based on the investigation research of weathering characteristics and affecting factors of weathering action on surrounding rock of the Longmen cavern, Luoyang, it is pointed that the main forms of weathering action are biological weathering and physical weathering. And the weathering meachanism is also studied. With the growing of plants on the top of the mountain, the primary effecting factor of weathering damage has beening changed into biological weathering from previous physical weathering. The biological weathering damage include mainly the mechanical damage of plant rootsystem and the biological-chemical damage of plant humic compounds. So the damage of biological weathering action should be paid more attention.
